ODMT Features 

Oscillator

·    Great phase noise: -147 dBc/Hz @ 1 kHz

·    Excellent stability, long and short term

·    Sine wave purity, low harmonic content

Bias Tee Mux (One for Horizontal/One for Vertical Polarity)

·    Highpass filtered L band:

rolloff below 900MHz, flat 950 thru 2100MHz

Assures DC block to Rx port and 10 MHz port

·    Filtered 10 MHz

·    Low thru loss from 10MHz input to LNB

·    Lowpass filtered DC, 1 Amp capacity,

2.5 Amp maximum option for transmitters

·    Any combination of 50W and 75W in/out Impedance transforms, (eg. 75W J-1 to 50W J-2)

·    Very low passband ripple

·    Very low L band through loss

·    Very high Rx port to 10MHz port isolation, no leakage back to rx

·    Superior Input and Output VSWR

·    Protects phase noise performance

·    Exceptionally low insertion loss

Functional

·    Will operate with LNBs, VSATs, BUCs, and Modems

·    Will eliminate loss of lock and bit error rate problems caused by poorly designed bias tees and ‘kluged’ solutions

·    Will reduce stray RF ingress into receivers/modems by filtering out all extraneous signals except the desired L band signal

·    Will insure that high level 10 MHz signals are delivered only to the LNB and not back to the receiver or modem.

·    Will filter and condition the DC power to eliminate extraneous signals coming in through the power supply.

Structural

·    Machined from solid aluminum billet for strength and stability

·    Allodyne finish for corrosion protection and excellent RF shielding/grounding

·    Cannon to BNC adapter cable available

·    'Back O Rack' mounting for ease of installation and lead dress (Reduces the mess of cables at the back of the rack and provides stability for cables)

·    Fewer cables and connector yields less signal degradation

·    Connectors are ‘O’ ring sealed for weather resistant operation

Orbital Benefits:

A single 10 MHz Oscillator to discipline both your Vertical and Horizontal signals – Excellent phase noise and stability, integrated with a set of filtered multiplexers and bias tees.  ODMT provides the optimum price/performance benefit.  One box plug and play!

 ·    Lower cost, higher quality with a one-box solution

·    No labor to source, assemble, and test a "Kluge"

·    Custom design variations available

·    Custom labeling requirements welcome
