An optimized single-pole double-throw (SPDT) transmit/receive (T/R) switch has been fabricated using depletion-layer-extended transistors (DETs) in a 0.18 /spl mu/m CMOS process. The switch features the highest performance to date of any switch using

Since an even harmonic mixer is pumped by LO with half the frequency compared with the fundamental mixer, LO can be generated and amplified easily with lower current consumption. When it is applied to the quadrature mixer (QMIX) or the image rejectio
