Abstract :
An energy efficient K-band GaAs-HBT amplifier applicable in a highly integrated direct receiver concept for sensor networks is presented. The preamplifier in a direct receiver is the most important building block and mainly determines sensitivity and energy consumption. Special issues of the amplifier design related to the receiver concept are highlighted in this paper. The presented amplifier shows gain of 14 dB and a noise figure of 6 dB using 47 mW DC supply.
