1.1  Introduction
The AMP-3A130-25 provides the final stage of RF amplification and filtering for the AM amplifier
AMP-3A130-25, 118 - 138 MHz  family. The amplifier covers 118 - 138 MHz with continuously
adjustable 10.0 to 25.0 W of output power.
The amplifier is packaged in the compact Eurostandard (5"h x 2.8"w x 7.5"d) housing, and is
robustly designed for mountain top or transportable applications.  The amplifier modules use high
reliability components and each is accompanied with a complete operational test report on delivery.
