Two Channel 400MHz Cell Enhancer User Handbook Handbook Nō.-50-128501HBK Issue No:-A Date:-12/08/2005 Page:- 11 of 39 2. OVERVIEW/SYSTEM DESCRIPTION This equipment is designed to enhance one 275kHz spaced channel in the 400MHz UHF band, and one IF select channel having 1.45MHz bandwidth also in the 400MHz band using 5 and 1Watt amplifiers on the downlink and uplink paths respectively. An RS232 controller/monitor together with a modem is fitted to provide remote monitoring of all active alarms and to allow remote re-configuration of channel module frequencies. See the RS232 controller/monitor handbook (17-005801HBKM) for more details on this feature. Two Channel 400MHz Cell Enhancer User Handbook Handbook Nō.-50-128501HBK Issue No:-A Date:-12/08/2005 Page:- 17 of 39 4. SUB-UNIT MODULES 4.1 UHF Notch Filter (02-020001) 4.1.1 Description The notch reject filters fitted here are tuned to eliminate the unwanted channel frequencies of the band 1 amplifier (where the filters are fitted in the band 2 path and vice-versa). The filters should require no routine maintenance, being totally passive devices. If a filter is suspected of failure, no invasive measures are recommended as even opening the case of the device could render it unusable. 4.1.2 Technical Specifications PARAMETER SPECIFICATION Passband1 492.5-494 & 490.6MHz Passband2 481-489 & 496.3-496.6MHz Stopband1: 496.3 & 496.5MHz Stopband2: 492.5-494, 496.3-496.6 & 494-494.5MHz Insertion Loss: 0.6dB typical Rejection: 40dB typical Power Rating 50 Watt Impedance 50Ω VSWR Better than 1.22:1 Two Channel 400MHz Cell Enhancer User Handbook Handbook Nō.-50-128501HBK Issue No:-A Date:-12/08/2005 Page:- 18 of 39 4.2 Bandpass Filters (02-011204 & 02-013401) 4.2.1 Description 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 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. 4.2.2 Technical Specification FILTER 1 489.5-491 MHz (02-011204) FILTER 2 496.3-496.7 MHz (02-013401) FILTER 3 492.5-494 MHz (02-011204) Passband: FILTER 3 499.3-499.7 MHz (02-013401) FILTER 1 3.0 dB (02-011204) FILTER 2 3.5 dB (02-013401) FILTER 3 3.0 dB (02-011204) Insertion Loss: FILTER 3 3.5 dB (02-013401) FILTER 1 MAX(>40dB) (02-011204) FILTER 2 MAX (>40dB) (02-013401) FILTER 3 MAX (>40dB) (02-011204) Isolation: FILTER 4 MAX (>40dB) (02-013401) Impedance:50 ohm Two Channel 400MHz Cell Enhancer User Handbook Handbook Nō.-50-128501HBK Issue No:-A Date:-12/08/2005 Page:- 19 of 39 4.3 30dB Power Monitor (07-012501) 4.3.1 Description The purpose of these couplers is to tap off known portions (usually 15-30dB) of RF signal from transmission lines at the antenna ports, either resistively or by induction, 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 formally known as directional couplers as they couple power from the RF mainline in one direction only. Various constructional techniques are used depending on the specification required. These include microstrip, stripline, coaxial cable and capacitive types. 4.3.2 Technical Specification PARAMETER SPECIFICATION Frequency range: 350 – 550MHz Insertion Loss: <0.3dB Coupling level: -30dBc Rejection: N/A Weight: <200gms Connectors: N type, female operation: -10°C to +60°C Temperature range: storage: -20°C to +70°C 4.4 ¼Watt 0- -30dB Switched Attenuator (10-000701) 4.4.1 General Application In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 4.4.2 Switched Attenuators The AFL switched attenuators are available in two different types; 0 – 30dB in 2 dB steps (as in this case), or 0 – 15dB in 1 dB steps. The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in. They are designed to maintain an accurate 50Ω impedance over their operating frequency at both input and output. Two Channel 400MHz Cell Enhancer User Handbook Handbook Nō.-50-128501HBK Issue No:-A Date:-12/08/2005 Page:- 20 of 39 4.5 Low Noise Amplifier (11-007402) 4.5.1 Description The 30dB gain low noise amplifier used is a double stage solid-state low-noise amplifier. Class A circuitry is used in the unit to ensure excellent linearity over a very wide dynamic range. The two active devices are very moderately rated to provide a long trouble-free working life. There are no adjustments on this amplifier, and in the unlikely event of failure then the entire amplifier should be replaced. The amplifier features a dedicated, in- built alarm monitoring system which gives a TTL ‘open collector’ type switched signal on alarm, this is then integrated using a built-in relay to give a volt-free contact for summation into the main alarm system. 4.5.2 Technical Specification PARAMETER SPECIFICATION Frequency range: 380-500MHz Bandwidth: <140MHz Gain: 30-32dB 1dB Compression Point: +22dBm (typical) 3rd order intercept: +34-35dBm (typical) Input/Output return loss: >20dB Noise figure: <1.3dB Connectors: SMA female Supply: …
