The CHM1080-98F from United Monolithic Semiconductors is a Single Side Band MMIC Mixer that operates from 71 to 86 GHz. It has an integrated balanced sub-harmonic cold FET mixer with a LO buffer and is usable both for up-conversion and down-conversion (also compatible with baseband configuration). This mixer has an LO frequency range from 34.5 to 44 GHz and an IF output frequency from DC to 12 GHz. It provides an LO/RF isolation of 17 dB and an image rejection of 15 dBc. This mixer requires a DC supply of 3.5 V and consumes 90 mA of current.
The CHM1080-98F is manufactured on a pHEMT process and has a gate length of 0.10 μm. It is available in a surface-mount package (also available in chip form) that measures 3.43 x 1.5 x 0.07 mm and is ideal for E-band applications, particularly for the new generation of high-capacity backhaul.
