Custom MMIC adds two new GaAs Mixer MMICs
C and X-Band high IP3 I/Q mixer MMICs can be used as either image reject mixers or single sideband upconverters
Custom MMIC, a US developer of monolithic microwave integrated circuits, has announced two new GaAs High IP3 I/Q Mixer MMICs covering C and X-Band, the CMD257C4 and CMD258C4.
These new mixers are said to feature wide IF bandwidths and excellent image rejection, compact 4x4 SMT packages and offer cost savings compared to hybrid image reject mixers and single sideband upconverter assemblies
The CMD257C4 offers a wide IF bandwidth from DC to 3.5 GHz, and an RF and LO bandwidth from 6 GHz to 10 GHz. This mixer features an image rejection of 31 dB, and a low conversion loss of 5.2 dB.
The CMD258C4 delivers an image rejection of 29 dB, and a low conversion loss of 5.5 dB. This mixer's RF and LO range also covers C-band and X-band frequencies, from 7.5 GHz to 13 GHz, with a wide IF bandwidth of DC to 3.5 GHz.
Both the CMD257C4 and CMD258C4 can be used as either image reject mixers or single sideband upconverters, and are composed of two double balanced mixer cells and a 90 degree hybrid. An external IF hybrid is needed to complete the image rejection.
These MMIC mixers come in leadless surface mount packages, and are designed to operate within specification from -40degC to 85degC.
