Bandpass Filter (02-007206) The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture in order to optimise the insertion loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50Ω load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification PARAMETER Response type Frequency range Bandwidth Number of sections Insertion loss VSWR Connectors Power handling Temperature operation range storage Weight SPECIFICATION Chebyshev 800 - 950MHz * 25MHz * 1.2 dB better than 1.2:1 SMA female 100W max -20°C to +60°C -40°C to +70°C 3 kg (typical) *tuned to Customer's specification 22.3.1.4. 4 Port Hybrid Coupler (05-003007) This transmitter hybrid coupler is a device for accurately matching two or more RF signals to single or multiple ports, whilst maintaining an accurate 50Ω load to all inputs/outputs and ensuring that the insertion losses are kept to a minimum. Any unused ports should be terminated with an appropriate 50Ω load. In this specific instance one port of 4 Port Hybrid Coupler (05-003007) is terminated with Dummy load 09-000902 (see below). 05-003007 Specification PARAMETER Frequency range Bandwidth Rejection Insertion loss Connectors Weight Temperature operational range storage SPECIFICATION 700-900MHz 200MHz >14dB 6.5dB (in band, typical) SMA <1.0kg -10%C to +60%C -20%C to +70%C STTRS DOCUMENTATION Document Number 80-330501HBKM – Issue A - Draft Page 414 of 500 22.3.1.5. Wideband Asymmetric Coupler (07-015105) The purpose of Wideband Asymmetric Coupler (07-015105) is to tap off a known portion (in this case 30dB) of RF signal from transmission lines and to combine them, for example through splitter units for different purposes (alarms/monitoring etc.), whilst maintaining an accurate 50Ω load to all ports/interfaces throughout the specified frequency range. They are known formally as directional couplers as they couple power from the RF mainline in one direction only. 07-015105 Specification PARAMETER Construction Frequency Through loss Coupling level Isolation Weight Connectors Temperature operation range storage SPECIFICATION Inductive air gap 800-2500MHz 0.4dB (typical) -30dB ±0.5dB N/A <1.0kg SMA, female -20°C to +60°C -40°C to +70°C 22.3.1.6. Dummy load 09-000902 When a combiner system is used to split or combine RF signals, in many cases it is most cost effective to use a standard stock item 4, 6 or 8 port device where, in fact, only a 3 or 6 port device is needed. In this case 4 Port Hybrid Coupler (05-003007) has one of its ports terminated with an appropriate Dummy Load in order to preserve the correct impedance of the device over the specified frequency range. 09-000902 specification PARAMETER Frequency Range Power Rating VSWR Impedance Temperature Range RF Connectors Dimension Weight Finish RF Connector Environmental MTBF SPECIFICATION 0 - 2500 MHz 25 Watts continuous Better than 1.1:1 50 Ohms -20 to +60°C N Type female 110.3mm x 38.1mm x 485 grams Black Anodised N Type male IP66 >180,000 hours STTRS DOCUMENTATION Document Number 80-330501HBKM – Issue A - Draft Page 415 of 500 22.3.2. 800MHz 5 Cavity Combiner System (50-132205) 800MHz 5 Cavity Combiner System (50-132205) consists of 5 Dielectric Cavity Resonators mounted on two 3U rack mount panels, three on one panel and two on the other 800MHz 5 Cavity Combiner System (50-132205) List of Major Components Section 22.3.2.3.

Dielectric Cavity Resonator (04-003401) Cavity resonators are used in this system for their high Q factor response and power handling characteristics. Being finely tuned items, they can be prone to being de-tuned by mechanical shock or vibration therefore these units should be handled, stored and installed with care. Note that the cavities are coupled together using critical length harnesses. If any cable is to be changed the exact same length and type of cable should be used for replacement. 04-003401 Specification Specification Frequency Range Bandwidth Insertion Loss Return Loss Attenuation Power Handling (CW) Environmental Size Weight Connectors Temperature operation range storage Parameter 800 - 950MHz * 25 kHz* < 1.0 dB > 15 dB (at both ports) > 10 dB at Fc ± 1 MHz 20W IP54 124mm x 158mm x 157mm** 1.5 kg N female -20°C to +60°C -40°C to +70°C *Tuned to Customer’s specification **Height is dependant upon position of tuning plunger STTRS DOCUMENTATION Document Number 80-330501HBKM – Issue A - Draft Page 419 of 500
