Abstract :
Six 2 Watt AlGaAs/GaAs Heterojunction Bipolar Transistor (HBT) MMIC amplifiers have been combined using low loss, low temperature cofired ceramic (LTCC) splitting and combining networks. The six MMIC amplifiers were combined in a compact, testable, and producible assembly. The amplifier assembly produced 10 Watts peak output power and 30% peak power added efficiency (PAE) over an 8.0 to 14.0 GHz bandwidth. This wideband power amplifier has applications in solid state transmitters and transmit/receive (T/R) modules that require high gain, high power, high efficiency, and compact size.<>
