CHR3694-QDG
RoHS COMPLIANT
37-40GHz Integrated Down converter
GaAs Monolithic Microwave IC in SMD package
Description
The CHR3694-QDG is a multifunction chip,
which integrates a balanced cold FET mixer, a
time two multiplier, and a RF LNA including
gain control.
It is designed for a wide range of applications,
typically commercial communication systems.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes through
the substrate and air bridges.
It is available in lead-free SMD package.
A mirror version versus RF & LO access is
available as CHR3794-QDG.

37-40GHz Down Converter
CHR3694-QDG
Typical Measured Performances
Tamb = +25°C, VDX=VDL = 4V, Typical VGX = -0.9V & VGM= -0.7V, P_LO=1dBm
These values are representative of onboard measurements (on connector access planes)
as defined on the drawing 97445 page 16 for CHR3694-QDG and drawing 97342 page 17
for CHR3794-QDG. The board loss is estimated to 2 to 3dB in the frequency range.
