Abstract :
Two linearization methods: -Feed-back loop -Forward bias of base emitter junction are used in the design of L-Band linear amplifiers for multicarrier operation in view of achieving C/I figures in the range of 24 dB to 26 dB without significant sacrifice of the efficiency. These amplifiers are a key item of the satellite transponders devoted to the maritime traffic control (MAROTS) and of the future spaceborne L-band phased array systems.
