Abstract :
This letter presents an S-band 50-W low-temperature cofired ceramic (LTCC) transmitter module. The module is based on a gallium arsenide (GaAs) chipset that operates over the 2-3 GHz range and includes a 28-V single-chip power amplifier with integrated high-speed drain modulator. The transmitter has rise/fall times < 7 nsec, linear frequency tuning, and excellent thermal performance.
