OVERVIEW
Signal boosters extend radio coverage into areas
where abrupt propagation losses prevent reliable
communication. The system receives an RF signal,
raises its power level, and couples it to an antenna
so that it can be re-radiated. The TXRX model
6138X family of channelized signal boosters is
designed to operate in either the 700 or 800 MHz
range. Dual band models are available that include
both 700 and 800 MHz systems in the same enclo-
sure box. The system is based on a module design
with each module capable of handling 14 or 30 car-
riers in the uplink and downlink direction. The sig-
nal booster is available in a variety of
configurations as shown in Table 1. The product
model number is used to describe each configura-
tion available. Model number nomenclature is
described in table 1.
The size of the system can be tailored to the cus-
tomers needs by increasing or decreasing the
number of carriers used. Each module is bi-direc-
tional with one downlink and one uplink signal
branch. Each of the two branches in a module are
independently tunable to their required pass fre-
quencies via software interface. System specifica-
