40-Watt Power Amplifier
The ENETL2T/U is an RF power amplifier designed for use in the 216-222 MHz frequency range at up to
40 Watts. It is intended to serve as a 100% duty cycle amplifier for MDS TD and other radios operating in
point-to-multipoint repeater or base applications.
The power amplifier consists of an RF amplifier and PCB mounted to a heat sink, with a DC Power
interface, power control interface, and input/output RF connections on the sidewalls of the chassis. DC
power is supplied to the amplifier from a regulated and filtered DC source capable of supplying 10-16
VDC at a maximum current of 8 Amperes. The DC power source should be current limited or have a
protective fuse or circuit breaker.
