Design and Fabrication of RF Power Amplifier for L Band Radar Transmitter

In this study, a kind of RF power amplifier for L band radar transmitter was designed, which is an important component of "training platform for performance parameters testing of L band radar transmitters". First, the basic principles of RF amplifiers were analyzed. Then, according to the function requirements of "training platform for performance parameters testing of L band radar transmitters", two power amplifier circuits were designed, and the lectotype analysis was carried out for core chips. On this basis, Protel 99SE software was adopted to draw the schematic diagram and complete the circuit layout. Vector network analyzer was used to test the gain indicator of the designed power amplifier. The designing method has certain value for the design of power amplifiers of other frequency bands and other usages.
