CHM1290-99F
20-30GHz Sub-Harmonic Mixer
GaAs Monolithic Microwave IC
Description
The CHM1290-99F is a Multi-Function Circuit
which integrates a self biased LO buffer
amplifier and a sub harmonically diode mixer
for 2LO suppression. 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
grounds. This helps 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.
