CHM1193
K-Band Mixer
GaAs Monolithic Microwave IC
Description
The CHM1193 is a balanced Schottky
diode mixer based on a six quarter wave
ring structure. It could be use in receiver or
transmitter part.
This circuit is manufactured with the
Schottky diode process : 1 µm Schottky
diode device, air bridges, via holes through
the substrate, stepper lithography.
It is available in chip form.
An electrically identical chip with a mirror
drawing versus de LO side is available
under the part number CHM1192. These
two MMICs could be helpful in a TX, RX
architecture module.
