Mechanical Drawing

Oscillator

  • Great phase noise: -147 dBc/Hz @ 1 kHz
  • Excellent stability, long and short term
  • Sine wave purity, low harmonic content

Mux/Tee

  • Highpass filtered L band, rolloff below 900 MHz, flat 950 thru 2900 MHz
  • Low thru loss from 10 MHz input to LNB
  • Lowpass filtered DC, 4.0 Amp maximum
  • Any in, Any out Impedance transforms (eg. 75 Ω in, 50 Ω out)
  • DC block to Rx port and 10 MHz port
  • Very low bandpass ripple
  • Very low L band through loss
  • Very high Rx 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, BDCs, VSATs, BUCs, and Modems

Structural

  • Machined from solid aluminum billet for strength and stability
  • Anodized finish for corrosion protection and excellent RF shielding/grounding
  • Connectors are ‘O’ ring sealed for weather resistant operation
  • Jumpers for DC and 10MHz between Oscillator and secondary module provided by Orbital
  • RoHS & REACH compliant

Oscillator and Power Supply 

Orbital advises that a power supply for the Oscillator must be of good quality otherwise extraneous signals will be transferred to the Oscillator, which can degrade its performance.

Orbital provides 2 DC connectors on the Oscillator so that the input power can power the Oscillator and then is fed through to the other connector on the Oscillator, which powers the secondary device, if necessary. But when using this option, the customer must still adhere to the 15 to 24 VDC restriction of the Oscillator.

Benefits

  • Lower cost, higher quality with a one-box solution
  • No labor to source, assemble and test a ‘kluge’
  • Custom design variations welcome
  • Custom labeling requirements welcome

SIP Solutions

Systems Interface Products Although Combiners and Oscillators are also SIP products, we have narrowed the definition here to just include Bias Tees, Diplexers, Mux Tees, TTL Switches, Thru Tees, Dual Power Tees, etc.
Here are standard applications for each of these products. Here’s how to insert 10 MHz, insert DC, extract 10 MHz, block DC, extract DC, multiplex DC L band and 10 MHz, and perform impedance transforms while you do it.

Using a Hi Power Thru Tee to power a BUC Modem has DC power, but not enough to power my new BUC.
4 Way Combiner with 10 MHz Oscillator and Hi Power DC insert. I want to lock several modems to a single 10 MHz Oscillator, and insert high power DC to my BUC.
Orbital 2-way Combiner using 10 MHz from one of the modems and Hi Power Mux/Tee to insert DC power I have a pair of modems, one of which provides a 10 MHz reference, but I don’t have enough power from my modem for my new high power BUC.
Orbital Combiner/Divider stripping out the 10MHz from only one of two modems I have a pair of modems and I need to use the 10 MHz reference from one of them and split it. I need to take the L-Band signal from both modems and combine it with the 10 MHz reference. Now I need to insert DC power for a pair of high power BUCS.
Orbital Combiner/Divider using a MOS 10 MHz Oscillator I need to combine the L-Band signals from a pair of modems with an common, external 10 MHz source, and insert power to a pair of high power BUCs.
Using an Orbital Hi Power Thru Tee to circumvent a divider or switch My modem does not have sufficient DC to power my BUCs, and I can’t switch DC power to the BUC, what to do?
Horizontal/Vertical Polarity 1 for 2 Redundant System We need a system that will provide us with both horizontal and vertical polarities at Ku Band. In addition, the system must offer 1 for 2 redundancy.

Using a Bias Tee Using an Orbital MT-40 Mux Tee as a Bias Tee to insert DC Power to a BUC
Using a Diplexer Using an Orbital MT-40 Mux Tee as a Diplexer to insert a 10 MHz reference to a BUC
Using Redundant Power Tee Using an Orbital Redundant Power Tee provides inexpensive power supply redundancy.
Using a Thru Tee Using an Orbital Thru Tee to provide a separate DC power supply to the BUC, while passing the 10 MHz signal through from the modem.
