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

(1) Parameters are given in the following conditions: (See § Recommended assembly plan):
- LO port: 50 reference plan before 0.15nH bonding.
- RFa & RFb ports: 50 reference plan after 0.15nH bonding.
(2) Optimum IF load: 200 for conversion losses or 50 for noise figure (typically 2dB
improvement).
(3) Measured on 50 IF load. Mixer noise only, too high VSWRRFx may produce additional IF
noise due to LO AM noise detection.
(4) These specifications are guaranteed for VSWRRFx<2.0:1. Too high VSWRRFa produces LO
phase detection that affect mixer self-bias.
(5) The current VtempI has to be fixed by an external resistor.
