Power Amplifier and Transmitter 
Specifications
This chapter provides specifications pertaining to the power amplifier as a 
separate module.  It also includes a number of transmitter RF specifications 
which pertain to the combination of power amplifier and exciter.
The performance figures given in these specifications are applicable only to 
equipment operating as an integral part of a TB8100 base station.  These 
performance figures are minimum figures, unless otherwise indicated, for 
equipment operating at standard room temperature (+ 22° C to +28°C 
[+ 71.6°F to + 82.4°F]) and standard test voltage (28VDC).  
Where applicable, the test methods used to obtain these figures are those 
described in the ANSI/TIA-603-B-2002 and ETSI-EN specifications.  You 
can obtain further details of test methods and the conditions which apply for 
compliance testing in all countries from Tait Electronics Ltd.
