Development of a 600 MHz, 0.3 MW Power Combining System Using RF LDMOS Power Transistors.
Abstract
An all solid-state, compact RF power combining system was designed, constructed and successfully tested. The system consists of eighty 2 kW SSPA modules., cavity power combiner operating at TM01o mode in a cylindrical cavity, 40-way power equal amplitude/phase RF power divider, matched RF load, and 5 stage drive amplifiers. Analytic calculation and extensive numerical simulations were performed to find critical coupling condition of the cavity with 160 magnetically coupled loop antennas and a 6-1/8" coaxial output antenna. Measured cavity coupling parameters were in good agreement with simulation results.
