Chapter 1 General Description
1-1 Introduction
This manual contains general information, installation procedures, and specifications for the op-
eration and use of the Power Amplifier Radio Module (PARM). The manual is organized as fol-
lows:
Chapter 1 General Description with Specifications
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 25 MHz band modulated RF input signals (869-894
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:
• GMSK compliant
• 8-PSK compliant
The PARM is rated for an average output power of 40/30 watts with an EDGE signal and 40/30
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.

2-2.2 Alarm Descriptions
• High Temperature – A temperature monitor located inside the PARM indicates the
alarm status if the temperature exceeds the defined threshold.
• High Current - This alarm indicates when a high current is pending that could dam-
age the PARM if the system continues to operate.
