STTRS DOCUMENTATION Document Number 80-330501HBKM – Issue A - Draft Page 414 of 500 22.3.1.3. 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 SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz * Bandwidth 25MHz * Number of sections 8 Insertion loss 1.2 dB VSWR better than 1.2:1 Connectors SMA female Power handling 100W max operation -20°C to +60°C Temperature range storage -40°C to +70°C Weight 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 SPECIFICATION Frequency range 700-900MHz Bandwidth 200MHz Rejection >14dB Insertion loss 6.5dB (in band, typical) Connectors SMA Weight <1.0kg operational -10%C to +60%C Temperature range storage -20%C to +70%C
STTRS DOCUMENTATION Document Number 80-330501HBKM – Issue A - Draft Page 415 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 SPECIFICATION Construction Inductive air gap Frequency 800-2500MHz Through loss 0.4dB (typical) Coupling level -30dB ±0.5dB Isolation N/A Weight <1.0kg Connectors SMA, female operation -20°C to +60°C Temperature range storage -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 SPECIFICATION Frequency Range 0 - 2500 MHz Power Rating 25 Watts continuous VSWR Better than 1.1:1 Impedance 50 Ohms Temperature Range -20 to +60°C RF Connectors N Type female Dimension 110.3mm x 38.1mm x Weight 485 grams Finish Black Anodised RF Connector N Type male Environmental IP66 MTBF >180,000 hours

STTRS DOCUMENTATION Document Number 80-330501HBKM – Issue A - Draft Page 419 of 500 22.3.2.2. 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 Parameter Frequency Range 800 - 950MHz * Bandwidth 25 kHz* Insertion Loss < 1.0 dB Return Loss > 15 dB (at both ports) Attenuation > 10 dB at Fc ± 1 MHz Power Handling (CW) 20W Environmental IP54 Size 124mm x 158mm x 157mm** Weight 1.5 kg Connectors N female operation -20°C to +60°C Temperature range storage -40°C to +70°C *Tuned to Customer’s specification **Height is dependant upon position of tuning plunger
