A low-power, switchless, full-duplex bidirectionalamplifier operating in the 915 MHz (ISM band) is proposed.It is composed of two identical reflection amplifiers and one90◦,−3dB Branch Line Coupler (BLC). The reflection ampli-fiers are designed using low DC power consumption tunnel diodesand provide a measured reflection gain of 13 dB with consumedpower of only 178μW for -30 dBm of incident signal power. Thesereflection amplifiers are integrated with a miniaturized BLC toform a bidirectional amplifier that provides 9 dB of measuredtransmission gain and 22 dB of measured return loss.
