Orbital MT25/40 Mux-Tee (Bias Tee/Diplexer)

Orbital MT25/40 Mux-Tee (Bias Tee/Diplexer)

The Orbital Research “Mux-Tee” is a high-performance bias tee diplexer – but it does much more than insert DC current.

  • Small and compact passive device – no power required
  • 6 devices in 1: bias tee, 10 MHz multiplexer, both a bias tee and 10 MHz mux, DC extractor, 10 MHz demultiplexer, or combination DC/10 MHz extractor

Our Mux-Tees provide signal multiplexing and demultiplexing for military and commercial SATCOM applications. They are stackable with customizable form factors and connectors – and deliver extremely low VSWR for unparalleled impedance matching and minimal through loss.

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.  This product may be used in its standard orientation, (as shown), or in reversed position – to extract, rather than insert 10 MHz signals and DC current.

Warranty: 3 years, repair or replace defective product

Specifications

  • Highpass filtered L band:
    • rolloff below 900MHz, flat 950 thru 2100MHz
    • Assures DC block to Rx port and 10 MHz port
  • Filtered 10MHz
  • DC: 2.5A (12 to 24V) standard; 4.0A (12 to 48V) high power; 6.0A (12 to 24V) high current
  • Any combination of 50Ω and 75Ω in/out Impedance transforms, (eg. 75Ω J-1 to 50Ω J-2)
  • Very high Rx port to 10MHz port isolation, no leakage back to rx
  • Will not degrade phase noise performance
  • Exceptionally low insertion loss

Functional

  • Will operate with LNBs, BDCs, VSATs, BUCs, and Modems
  • Will operate in S-Band with 0.7 dB insertion loss (max) and in C-Band (3.4 to 4.2 GHz) with 1.0 dB insertion loss (max)
  • Has flexible sealant on lid-to-case interface; Connectors are O ring sealed. When properly sealing connectors with butyl tape, the Mux-Tee is ready for outdoor, weather resistant operation.
  • Will not cause loss of lock

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.

How to order

Each connector type has an impedance of either 50 or 75 Ω.  Orbital uses 1 of 4 distinct boards to achieve the appropriate impedance transform:

V1 – 50Ω to LNB/BUC, 50Ω to Rx/modem
V2 – 75Ω to LNB/BUC, 50Ω to Rx/modem
V3 – 75Ω to LNB/BUC, 75Ω to Rx/modem
V4 – 50Ω to LNB/BUC, 75Ω to Rx/modem
International customers should note that pricing does not include freight, brokerage, local VAT, and customs charges.  Prices from our dealers in your area usually include these amounts.

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.
