Abstract :
A K band GaAs-HBT mixer using a cascode structure is presented. Conversion gain of 4 dB can be achieved at 24 GHz with 4 dBm LO power. Power consumption is reduced to 9 mW, hence such mixers are applicable as central building blocks of highly integrated low power receiver front-ends in pico cell networks. Finally, a modification of the mixer is presented which achieves 12 dB conversion gain at a 50 Ω output port with 12 mW DC power consumption.
