Description

The CHM1290 is a MFC which integrates a self biased LO buffer amplifier and a subharmonically diodes mixer for 2LO suppression It is usable  both for up-conversion and downconversion. 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 grounds. This helps simplify the assembly process.
CHM1290 is manufactured with a PM-HEMT process, 0.25µm gate length, capacities over via holes, via holes through the substrate, air bridges and electron beam gate lithography.
CHM1290 is available in chip form.
