1-2. GENERAL DESCRIPTION
The G3L-800-25-001 (see figures 1-1 and 1-2) is a linear, multichannel power
amplifier that operates in the 25 MHz frequency band from 869 MHz to 894 MHz.
It is designed as a self-contained module with EMI containment for use in both
indoor and outdoor North American cellular base stations. The G3L-800-25-001
accepts single channel and transmit voice RF signals. The G3L-800-25-001 uses
an internally generated tone to optimize its performance. The system operating
band (A or B) is externally provided to the G3L-800-25-001 so that it knows where
the tone frequency is going to be. If the operating band is A, then a tone at B
band is generated; if the operating band is B, then a tone at A band is generated.
Each amplifier module has a power, alarm, and control connector that allows the
host system to monitor the amplifier module performance. Primary power for the
amplifier is +27 Vdc.
