LPA (   )  Power Amplifier Modules

These Power Amplifiers are designed primarily for use in repeaters and commercial transmitters to boost the 2.5W output of the exciter to a higher level.  In effect, these modules are used with an exciter to make a complete transmitter.

These amplifiers have enhanced harmonic filtering and B+ decoupling to avoid desense. They are biased for class-C operation for high efficiency; so they may be used on FM or CW modes. The LPA2-15R is FCC type accepted under parts 22, 74, and 90.

The PA is sold less heatsink; since it normally is mounted to the enclosure, which acts as a heatsink.  PA's are designed for continuous duty with 2.5 Watts input and operate on 13.6Vdc @ 2-2.5Amp.  Power output varies with model and frequency range, as indicated in the price list at the right.

Note: Wired/tested units require careful mounting to the chassis to avoid stressing the case of the transistor.  Download instruction manual for details.
