CHM1270a98F
W-Band Dual Channel Transmitter/Receiver
GaAs Monolithic Microwave IC
Description
The CHM1270a98F is a dual channel
self-biased transmitter/receiver. One RF port
used for reception and one for both emission
and reception. This product is designed for
optimum IF noise performances.
This circuit is well adapted to the sensors
system at W-Band, such as automotive long
range radar and industrial sensors.
This circuit is manufactured with the BES
MMIC process: 1 µm very high Ft Schottky
diode device, air bridges, via holes through
the substrate.
It is available in chip form with BCB top layer
protection.
Main Features
■ Very low 1/f noise
■ High LO/AM noise rejection
■ Low conversion loss
■ IF from DC to 100MHz
■ No DC bias required for mixer
■ On chip temperature sensor embedded
■ ESD strengthened
■ Chip size: 2.95 x 2.00 x 0.10mm
