An MHMIC K-Band Direct Conversion Demodulator in CPW

This paper presents results on a miniature hybrid microwave integrated circuit (MHMIC) direct frequency conversion demodulator in coplanar waveguide (CPW) for in-phase/quadrature (I/Q) applications at the 20 GHz radio-frequency (RF) band. The 4x7 mm2 converter was fabricated using flip-chip GaAs Schottky diodes in a single balanced configuration. It… (More)
