Abstract :
A 38-48-GHz miniature sub-harmonically pumped mixer has been developed using GaAs 0.15-/spl mu/m pHEMT technology. An anti-parallel diodes pair is used for frequency conversion with a low LO input power. Quasi-lumped matching topology is employed to minimize the chip size and cost. The mixer is fabricated in chip size 0.85 /spl times/ 0.85 mm/sup 2/, and exhibit 12-15-dB up-conversion loss and 11-16-dB down-conversion loss with 10 dBm LO power.
