Description
The TC231 is a 65 GHz integrat-
ed diode limiter that can be
used to protect sensitive RF
circuits from excess RF power,
DC transients, and ESD. Two
limiters are provided on–chip
to enable single–ended or dif-
ferential use.
The TC231 can be used as an
unbiased 10 or 18 dBm passive
limiter; it also provides adjust-
able limiting and peak power
detection capabilities.
The TC231 has been designed
for minimal insertion loss.
Group delay characteristics
have been optimized to allow
use in millimeter–wave analog
and gigabit digital designs.
