Orbital Design
Orbital Research's new version of its MuxTee is really a six in one combination all-purpose tool. It may not slice and dice, but it will act as a Diplexer (combining a 10 MHz reference signal and L-Band output into one feed to an LNB or BUC), or as a BiasTee (inserting and filtering external DC to the L-Band signal for the LNB or BUC), or as a MuxTee (that combines the external DC insertion of a BiasTee with the ability to multiplex an inserted 10 MHz reference source of a Diplexer). That accounts for three functions - if the Diplexer / BiasTee / Multiplexer is reversed, it can be used to extract the 10 MHz reference, or DC power, or both. In addition, it comes in standard and high power versions.
In its function as a MuxTee the MT25/40 Mux/Tee integrates the L-band and DC filters of the BT-1 Bias Tee with a 10 MHz Lowpass filter and an optional 20 MHz notch filter to multiplex a 10 MHz external reference oscillator signal to your LNB or transmitter. What previously took a mixed bag of separate components is now available in an integrated bandpass-filtered and power-conditioned one-box solution ready for 'Back O Rack' mounting.
The unused connectors do not need to be terminated and are 'O' ring sealed.
Just as a chain depends on it's weakest link, the integrity of your signal depends on every component through which it passes; bit do you consider your bias tee as part of that system? Every satellite signal you receive must go through your bias tee. Does your Bias Tee have the best loss, tilt, ripple, VSWR, filtering and port to port isolation available?

Mechanical Drawing
The Orbital MT25/40 Mux Tee is built for indoor mounting back-o-rack, but its 'O' ring sealed connectors and corrosion protection due to its Allodyne finish, also allow for outdoor use. The MT-25/40 functions as a Mux Tee, Bias Tee, or 10 MHz Diplexer, it can insert or extract the 10 MHz and DC signals, it can act as a DC block, it performs low loss impedance transforms, and filters and conditions the signals it multiplexes onto the Interfacility Link.
In addition to normal MT24/40 qualities such as being built for indoor mounting back-o-rack, and its 'O' ring sealed connectors and corrosion protection due to its Allodyne finish, also allows for outdoor use, the 433 Mux Tee also inserts and extracts a 433 MHz monitor and control signal onto the IFL. The MT433 functions as a Mux Tee, Bias Tee, or 10 MHz Diplexer, it can insert or extract the 10 MHz, 433 MHz and DC signals, it can act as a DC block, it performs low loss impedance transforms, and filters and conditions the signals it multiplexes onto the Interfacility Link.

Why would I want a Bias Tee Multiplexer?
- Most engineers are aware that with mux tees and diplexers, the phase noise performance of the system - specifically the local oscillator in the LNB, (or the local oscillator in the BUC), is totally dependent on the quality of the10 MHz oscillator. While you can buy a very high quality, very low phase noise, very stable product – getting from that oscillator to the LNB or BUC can create problems if not done correctly. For example, if you amplify and split the 10 MHz signal, you are going to have to ensure that the amplifiers are very low noise, that there is no VSWR issue, and that there is no contributed base noise issue. With an Orbital product taking over that task for you, you are assured of no added noise, no problems with, or distortion of the 10 MHz signal as it is going from the oscillator or to the LNB or the BUC.
- You've got a redundant switch, you need to power your LNBs separately, so one of them is always on and not being switched by the switch, so you use a bias tee, or a Mux for an external reference unit. Or you have a redundant system and you have to be sure that you're not switching your 10 MHz, because you'd use lose lock on the LNB you switched to. You have to have a splitter feeding to the LNB all the time, not switched, but to do that you need two Mux/Tees feeding 10 MHz constantly into the LNB, and only the output gets switched.
- Anytime you have to split a signal, go to multiple receivers or multiple modems, the safest way is a Mux/Tee or Bias Tee. Anytime you have to use multiple modems to feed a BUC use a Mux/Tee, or Diplexer if you are powering the BUC separately. An Orbital SIP product guarantees performance, filtering, conditioning, no degradation of signal, no ripple problems, and you can transfer impedances at will. Saves time, saves money, it raises system integrity, reliability, and performance.
- You're a sophisticated systems system integrator, you have field technicians, you have system engineers in the field, and you've got a lab – what are they using for test purposes? They should each have a bias tee mux in their tool kit, to able to insert and test systems so that they can be assured that there is no problem with bias tee, or they can use it to isolate and diagnose system problems. So there should be a bias tee/mux in every toolbox.
- In the lab you have to assure quality measurements, sometimes accurate to better than a tenth of a dB - this is where SIPs really shine. Lab grade products come complete with plots that will indicate the exact loss at each frequency. It will indicate the insertion loss of the 10 MHz, it will give you the isolation value of the 10 MHz back to the receiver, and will assure best match between each of the components on your bench as you're testing the equipment. In other words, you can trust the results you get by using this device to insert - that applies to noise figure measurements, gain, ripple, temperature measurements, anything you're testing in the lab, is enhanced and made more certain by using an Orbital Mux/Tee.
- One of the issues we faced was that we were not very satisfied with the quality of the connectors available in the satellite industry. You can buy very good connectors at a $150 each, and you can get very poor quality connectors all in the same system, yet the signal is serial, it goes through each one of these connectors, good and bad. The reliability of your system is equal to the reliability of the weakest link in your serial signal chain. The lowest common denominator is going to be your floor of reliability. Therefore we elected to build our own specially designed connectors, that are interchangeable, to allow low-cost production and re-configuration to different impedances and different connectors, and to provide top quality performance above two GHz, which is not the norm, for example, for F connectors. So, by taking control of the connector interface and standardizing its mounting system, we have been able to provide you with maximum choice and flexibility at minimum cost, and yet maintain standards of performance that are redefining the industry standard.
- Consistency and reliability, from system to system in large networks, whether they are VPNs or business networks or broadband networks is essential. Being able to standardize on a high quality, reliable and repeatable product is important in your overall system five nines reliability. Remember, quality of service is an important metric these days. The cost of a service call, the cost of a failure, the downtime of a satellite system, it doesn't matter what fails, whether it's a thousand dollar component, or a one dollar component – you are still down. You can count on the reliability of the Orbital Mux Tee. It will be the same in Brazil, in the North West Territories, in South America. at the south pole, in Equatorial Africa, on the Saudi desert, it will work the same no matter where you are. You are able to get interchangeability of all of your components because you know that you are connecting to a gold standard product.
- Documentation in commissioning the system is also important for large earth-station customers. Orbital, with its state of the art lab, and industry standard equipment from vendors such as Hewlett Packard, Rose and Schwartz, Agilent, Anmitsu, maintain the highest standards of testing and certification of their product. We can provide plots and back up every measurement that we make, not with just figures on a page but with actual measured instrumentation and plots of performance – so that you can introduce these into your commissioning documents, to verify and validate the performance specifications that are claimed. This is particularly important for any Intelsat earth-station, any large scale telecom earth-station, and military applications where system documentation and performance and the ability to log the aging of a system is a matter where you have to have well-documented references or starting points

The Orbital MT25/40 is a Bias Tee (and a Diplexer, and a Mux Tee...)
Orbital MT25/40 Mux Tees function as Bias Tees (inserting DC power into the combined signal), as Diplexers (inserting 10 MHz into the combined signal), and as Mux/Tees inserting both DC power and 10 MHz reference). The MT25/40 will also act as a DC block on the combined input port - thus allowing DC to be inserted. It can also act as a low-loss impedance transform, depending on which connector combinations are chosen.
MT25/40's also work in both directions - in reverse position they can extract L-Band or 10 MHz signals.
The MT25/40 has less than 0.5 dB of insertion loss and filters and conditions its incoming signals. It is the fundamental component of Orbital's signal routing solutions.
