POWER AMPLIFIERS
The standard RF power output of the P25 transmitters is adjustable from 2 to 8 Watts. If a higher RF
power output is required, the transmitter may be used as an exciter to drive a power amplifi er. Daniels
Electronics manufactures a 30 Watt power amplifi er, shown in Figure 6-8, that will fi t into a standard
subrack.

Daniels Electronics can also supply higher power amplifi ers (60 W, 100 W, 250 W) that are 19” rack
mountable.
TUNING AND MAINTENANCE TOOLS
To facilitate testing, alignment and maintenance for the MT-4 radio systems, extender cards can be
used to extend the individual modules out from the subrack. Extender kits (extender card plus a four
foot cable) allow the modules to be extended out to a bench for servicing.
The following extender cards and kits are available:
EC-96D1 (direct connect) or EC-96K-1.22 (card and cable)
Used for the 96 pin control cards (CI-RC-4L and CI-BC-4E).
EC-48RD (direct connect) or EC-48RK-1.22 (card and cable)
Used for all transmitter, receiver, power amplifi er and system monitor modules.
The A-TK-04 tool kit includes a number of spare parts for the MT-4 radio system, including tuning
tools, guide rails, transient suppressors, diodes, a fuse, dust caps, shunt jumpers, ESD wrist strap, and
various screws and hardware.
