Abstract :
An energy efficient K band GaAs-HBT mixer applicable in integrated receiver front ends is presented. For pico cell networks, reduction of energy consumption is a central task. This mixer operates with a power as small as 15.6 mW still providing adequate gain making it in some cases unnecessary to use an amplifier. The mixer provides 13.5 dB power gain at 24.5 GHz using 0.5 dBm LO power. Compared to reported K band mixers employing other architectures, this is an excellent performance.
