General Description
The Qorvo TGC4603-SM packaged MMIC combines a
frequency doubler with a multi-stage amplifier, operating
at input frequencies of 13.5 - 16 GHz. With greater than
70 dBc isolation between the input and the doubled output
frequency, the TGC4603-SM achieves more than 1 Watt
output power, with only 3 dBm input power. This
performance makes this doubler ideally suited for Ka-
Band satellite ground terminal applications. The
TGC4603-SM provides the frequency doubling function in
a compact 5 mm x 5 mm package footprint.
The TGC4603-SM is RoHS compliant.
Evaluation boards are available upon request.
