CHR2294

CHR2294 RoHS COMPLIANT 25-35GHz Single Side Band Mixer Self biased GaAs Monolithic Microwave IC Description The CHR2294 is a multifunction chip (MFC) which integrates a self biased LO buffer amplifier and a sub-harmonically balanced diodes mixer for 2LO suppression and image rejection. It is usable for both up-conversion and down-conversion. It is designed for a wide range of applications, typically commercial communication systems for broadband local access. The backside of the chip is both RF and DC grounded. This helps to simplify the assembly process. The circuit is manufactured with a pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.
