CHR2421-QEG
RoHS compliant
23.75-24.5GHz Dual Rx Channel
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHR2421-CHR2421-QEGQEG is a
monolithic
multifunction
dual
channel
receiver in K-Band which integrates low
noise amplifiers and mixers providing an IF
signal from DC to 1 MHz. All the active
devices are self biased on chip.
The circuit is dedicated to sensors and also
well suited for a wide range of microwave
and millimetre wave applications and
systems.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length.
It is supplied in a 24 leads RoHS compliant
QFN4x5 package
.
