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 (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.
