Installation & Service Manual
Chapter 1 General Description
1-1 Introduction
This manual contains general information, installation procedures, and specifications for the operation and use of the Power Amplifier Radio Module (PARM). The manual is organized as follows:
Chapter 1
Chapter 2 Installation and Operation
1-2 General Description
The PARM is designed as an integrated subassembly unit mounted in a Radio Module (RM)
closed metal housing fitted with a heat sink and connected by RF coaxial and DC connectors.
The PARM use a common DC/DC converter for operating power. Up to three PARM can be
mounted in one RM.
The PARM’s basic function is amplifying two 60 MHz band modulated RF input signals (18501910 MHz and 1930-1990 MHz) from the TX driver subassembly, up to the level of the whole
transmitter, as defined in GSM 05.05, class 1 (20 watts minimum and 40 watts maximum). The
main characteristics of the PARM are:
General Description with Specifications
• GMSK compliant
• 8-PSK compliant
The PARM is rated for an average output power of 30 watts with an EDGE signal and 30 watts
with a GMSK signal. The electrical specifications are also designed to be in compliance with the
requirements of GSM 05.05.
1-3 Specifications
Specifications for the PARM are listed and described in table 1-1.
