EBTS System Manual - Vol 2 Base Radio Exciter

QUAD Channel 900 MHz Exciter

QUAD Channel 900 MHz Exciter Overview

The Exciter and the Power Ampliﬁer (PA) provide the transmitter functions of the

QUAD Channel 900 MHz Base Radio. The Exciter module consists of a printed

circuit board, a slide in housing, and associated hardware. The BRC shares the

printed circuit board and housing.

The Exciter connects to the Base Radio backplane through a 168-pin connector

and two blindmate RF connectors. Controller and exciter circuitry also

interconnect on the Exciter/Controller module. Two Torx screws on the front of

the Exciter secure it to the chassis.

An LED identiﬁes the Exciter’s operational condition, as described in the

manual’s Controller section. The Base Radio section of the manual provides

speciﬁcations for transmitter circuitry. This information includes data on the

Exciter and PAs.
