Description

The CHM1291 is a multifunction chip (MFC) which integrates a LO buffer amplifier and a subharmonically balanced diodes mixer for 2LO  suppression and image rejection. It is usable both for up-conversion and down-conversion. It is designed for a wide range of applications, typically commercial communication systems for broadband local access (LMDS). The backside of the chip is both RF and DC grounded. This helps simplify the assembly process.
CHM1291 is manufactured with a PM-HEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.
CHM1291 is available in chip form.
