Bird Technologies group, TX RX systems brand time-proven combiners and multicouplers provide design security for any multi-channel radio system. From the most complex multi-site homeland security system to the simplest 2-channel private system, our products enables unsurpassed flexibility to accommodate the most challenging frequency plans, as well as future expandability. The same architecture used for transmitter combining can also be used as a preselector in complex receive systems where there is not sufficient guardBand to use combline bandpass filters. Proven low-loss and low PIM construction techniques are used such as welded cavity construction; silver- plated loops, Alballoy®- plated integrated loop plates and connectors; as well as a unique fingerstock-free high conductivity silver- plated tuning probe. Our patented internal temperature compensation insures that transmitter cavities remain in tune even when connected to high duty cycle transmitters. Coupled with either peg rack or 19” rack and TX RX’s own high-isolation transmitter isolators, the TX RX combining and multicoupling system continues to hold its position as the gold standard in the demanding private and public safety market. All TX RX products are designed and manufactured in the USA.
TX RX provides multicoupling systems, not “one-size-tries-to-fit-all” products. Each system is designed and configured for the specific site at which it is to be used. Intermodulation studies as well as transmitter noise and receiver desense estimates are used to design the unit with the required isolation characteristics for the environment where it will be used.
T-Pass®- BroadBand architecture of the T-Pass® circuit and coaxial cavities mitigates equipment obsolescence and facilitates ease of system reconfiguration when re-banding is necessary- Each system is configured for optimum performance- Ideal for applications with minimal guard band between transmit and receive frequencies
* IF YOU DO NOT FIND A T-PASS COMBINER CONFIGURATION THAT MEETS YOUR NEEDS PLEASE USE THE T-PASS NOMENCLAUTRE TABLE ON PAGE 6 TO VIEW ADDITIONAL AVAILABLE MODELS. Star-Junction- High performance specifications with narrow adjacent channel spacing and low insertion loss- 5.8” square cavity or 8” round cavity with 19” rack mount configuration for space efficiency- Same length interconnect for ease of retuning and expansion in the field
Airline Junction- Airline Junction Combiner Series can be configured from 2 to 6 channels. - High performance specifications with narrow adjacent channel spacing and low insertion loss. - Models are available to support 764-869 MHz and 926-960 MHz.
Compact Ceramic Combiner - Ceramic TX Combiners combines many transmitters onto a single antenna. - Footprint that’s more than 50% smaller than comparably performing 10” cavities. - Optimizes valuable space for your radio equipment, which in an era of escalating lease costs, makes it the perfect combining solution.
Control Station- Multi-channel combiners provide frequency-agile operation across their entire frequency range. - May be used to reduce the number of antennas required on a communications site while also ensuring that predictable radio-to-radio isolation is maintained at all times - irrespective of individual radio’s Tx or Rx operating mode or antenna isolation characteristics.

The typical channel losses specified here are for equally-spaced channels only. Channel loss may be higher or lower in multicouplers where separation varies from one channel to another. Contact TX RX systems for T-Pass® channel loss specifications based on your actual system frequency plan.
T-Pass Selectivity vs. Cavity LossAs in the case of bandpass cavity filters, T-Pass® filter selectivity depends on the coefficient of coupling of the cavity loops at resonance. Tighter coupling decreases insertion loss and selectivity; loose coupling increases them. Although 746-869 MHz T-Pass® cavity loops can be set to approximately -0.8 to -3.0 dB insertion loss at resonance, TX RX Systems Inc. uses two “standard” cavity loss settings, -1.25 and -1.80 dB, that produce adequate selectivity for the majority of multicoupler applications in this range. The curves shown here represent the lower-selectivity side of the response curve of a typical 6.625-inch diameter, 3/4-wave 770 MHz T-Pass cavity filter.
Bridging loss in a progressive thruline T-Pass structure varies in the same general manner as bridging loss in a parallel junction bandpass structure: it decreases as cavity selectivity increases. An optimal cavity loss setting exists that minimizes channel loss under a specified frequency plan and number of channels. See Tech-Aid no. 92002 (lit. no. d3001d93) for a complete set of selectivity and bridging loss curves for T-Pass cavities from 66-960 MHz.

T-Pass Combiner Expansion Channels
Expansion Channel Description - A 6.625” or 10” 3-quarterwave T-Pass® cavity filter - A dual ferrite isolator, with RF loads and coaxial cable for connection to the cavity - An RF sampler to measure RF power reflected into the isolator output load isolator and channel mounting hardware. “Expansion assemblies for channel 2 and higher are supplied with a thruline of the correct length for the new channel frequency. Starter channels (channel 1, bottom) are supplied with a short circuit on the T-Pass loop.” Ordering Information To order an expansion channel, specify the following:1. Frequency and position of all channels in the system to be expanded 2. New Channel Frequencies 3. Transmitter output power on all new channels T-Pass® expansion Channel Guide Tech-Aid No. 93002 (lit. no. d3011F93) provides a listing of expansion channels by frequency range and isolator load power, as well as diagrams to facilitate selection of the correct channel configuration. Expansion channels are also available with 60-watt loads. Consult with factory.

T-Pass Combiner Racks
T-Pass racks provide a simple and secure mounting for our expandable cavity multicoupler systems. They are constructed of alodined aluminum except for the steel gussets and cavity support pegs. Shipment is usually made in six sub-assemblies and completed on site. Racks under 66” in height can be shipped UPS. Various rack models are required to accommodate the different cavity diameters and resonator lengths. The chart below provides the principle dimensions for space and mounting considerations.
Depending on the frequency band, the tuning rods will extend beyond 9” ~ 12” beyond one of the uprights. For clearance consideration, use do + 12” for the overall depth.
- Aluminum channel 3” x 1” x .125” wall- Solid aluminum bar 1.25” x 1.5”- Triangular steel gusset 9” x 9”- Spare open circuited stub for 800 MHz system, all others are short circuits
