Complete Transmitter
57-66 GHz
Rev.A04-14
Description
Applications
60 GHz point-to-point radio
Active imaging
General purpose
The gTSC0020 is a highly
complete integrated transmitter for
60 GHz radio applications. It
includes a II_QQ_mixer with low
conversion loss and high linearity,
a x6 frequency multiplier, an
active variable attenuator, a
power amplifier and a temperature
compensated power detector.
