Specifications

  • Highpass filtered L band:
    • rolloff below 900MHz, flat 950 thru 2100MHz
    • Assures DC block to combined port and Digital port
  • DC: 2.5A (12 to 24V) standard; 4.0A (12 to 48V) high power;
  • Any combination of 50Ω and 75Ω in/out Impedance transforms,
    (eg. 75Ω J-1 to 50Ω J-2)
  • Will not degrade phase noise performance
  • Exceptionally low insertion loss for L band and 10 MHz

Functional

  • Will operate with LNBs, BDCs, VSATs, BUCs, and Modems

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 Mux Tee Using an Orbital MT-40 Mux Tee to multiplex the L-Band, and 10 MHz reference signals with DC power for a BUC.
 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.
