A High-Power Solid-State C-Band Transmitter for MlS Applications
W.C. Tsai, Robert Gray, M.I. Grace · 2005
A solid-state C-band transmitter was developed for the Microwave Landing System. The key component of the transmitter is a solid-state power amplifier using GaAs Read-profile IMPATT diodes to obtain operating output levels approaching 20 Watts. The transmitter also contains a phase-locked oscillator, a phase modulator integrated into the power amplifier, and a pulse shaping network to achieve minimum spectrum spreading. The entire transmitter, including power supplies, logic circuits and heat sinks, is contained in a 12" x 12" x 6-1/2" package.
