Product Description
The TriQuint TGC4702-FC is a down converting IQ
mixer designed to cover the automotive radar
frequency band.
The TGC4702-FC typically provides 12 dB
conversion loss from 75 – 82 GHz to an IF
frequency band of DC – 100 MHz. The TGC4702-
FC is designed using TriQuint’s proven HBT
process and front-side Cu / Sn pillar technology for
simplified assembly and low interconnect
inductance. Die reliability is enhanced by using
TriQuint’s SiN passivation process.
Lead-free and RoHS compliant.
