RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 1 of 5 TMPRM PCS 1900 50W GMSK 30W EDGE Model: RF100721 (RM2 1900) Doc: PT08001 Operation Instruction Date: May 18, 2008 Version. 1.0 Ref# : FCC ID:S8L-100721TMPRM & IC:2237-100721TMPRM
RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 2 of 5 1. Introduction This document presents description of the Andrew Corporation 1900 PCS Band RM2 Power Amplifier (50W GMSK / 30W EDGE). The RF100721 (RM2 1900) amplifier is a medium power, RF amplifier intended to provide signal amplification. The RF100721 (RM2 1900) amplifier is compatible with GSM and EDGE air interfaces operating in U.S. domestic cell sites where FCC compliance is mandatory. The RF100721 (RM2 1900) power amplifier includes 3 lines of RF amplification (“TX paths”). Each TX path is capable of supporting both GMSK and EDGE standards on the PCS band (1930 MHz to 1990 MHz). Each TX path is rated for 30W output with EDGE signal, and 50W with GMSK signal. 2. RF100721 (RM2 1900) Specifications The RF100721 (RM2 1900) provide linear amplification of single-carrier signals in the PCS frequency band. The RF100721 (RM2 1900) have the following specifications for each TX path: Parameter Specification Operating RF Band 1930-1990MHz In band RF gain 48dB Input signal types GSM or EDGE single carrier Input DC Power 28 VDC +/-1%, nominal DC voltage input range 26VDC to 30.5VDC Rated Output Power @ 28VDC +/-1% & GMSK signal 50W average Rated Output Power @ 28VDC +/-1% & EDGE signal 30W average DC-Power Consumption @ GMSK signal & rated output power 170W (29% Power efficiency) DC-Power Consumption @ EDGE signal & rated output power 150W (20% Power efficiency) Physical dimensions 11.5” x 16.15” x 2.4” Weight < 12.13lbs Cooling technique External cooling when the Amplifier is placed in the customer frame. Temperature Range -5°C to +60°C (heat sink inlet air), meeting specifications. Table 1 RF100721 (RM2 1900) Specifications
RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 3 of 5 3. Functional Blocks: The Andrew RF100721 (RM2 1900) includes 3 lines of RF amplification. Each of them contains the following functional areas: − Power Amplification Line-Up − Power Conversion and Conditioning Circuit − Monitoring and Control Circuit
RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 4 of 5 4. Inputs and Outputs: The amplifier is powered from a DC supply voltage, which can range from 26VDC to 30.5VDC. The DC power is brought into the amplifier through a header right angle, 2 pins connector, located on the amplifier motherboard. A 44 pins connector, also located on the amplifier motherboard, is used for analogical lines enabling monitoring and control. This connector is used both during factory tests and at the system level by the customer . The 3 RF input signals are brought into the amplifier through 3 female SMA type connectors located on the amplifier motherboard. The 3 amplified RF signal are brought out of the amplifier through 3 N type connectors. They are located on the face plate of the amplifier. 5. Control System: The RF100721 (RM2 1900) power amplifier is controlled by the customer logic board, which builds control signals and accepts monitoring signals. This additional board is also responsible for the whole transmitter external digital / analogical interfaces. A controller is used at system level to control the amplifier alarm system (by monitoring temperature and currents for each TX paths) and to compensate the environmental drift (ambient temperature). 6. Installation and Operation Set-Up The RF100721 (RM2 1900) is easy to operate and use, only requiring a special cables for DC power and interface connection into the customer frame. RF input and output connections are done with industry standard SMA and N connectors. 7. FCC & IC Statements: FCC ID:S8L-100721TMPRM This device complies with Part 2, 15 & 24 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation. IC Information: Trade Name: ANDREW CORP, High Efficiency Power Amplifier TMPRM1900 Model No.: RF100721 IC: 2237F-100721TMPRM This device complies with RSS-131, RSS-102 of the IC Rules. Warning
RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 5 of 5 Changes of modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipments.
