Abstract:

A compact monolithic C-band direct conversion receiver has been implemented in a commercial 0.6-µm GaAs MESFET process. Subharmonic mixing is utilized to suppress even-order intermodulations and eliminate dc offsets. Second-order input intercept point (IIP2) of +17 dBm, third-order input intercept point (IIP3) of +8 dBm, and dc offset of -80 dBm are measured on wafer without the use of additional off-chip components. This receiver occupies a die area of 35 × 53 mil2 and operates on 2.7 V with 21 mA of dc current. This is the first demonstration of a C-band direct conversion receiver MMIC with excellent linearity, dc offset, and dc power consumption.
