17 - 20 GHz 10 W GaN Power Amplifier
Product Overview
Qorvo’s TGA4548 is a high frequency, high power MMIC
amplifier fabricated on Qorvo’s production 0.15um GaN on
SiC process (QGaN15). The TGA4548 operates from 17 –
20 GHz and typically provides 10 W saturated output power
with power-added efficiency of 30% and large-signal gain
of 22 dB. This combination of high frequency performance
provides the flexibility designers are looking for to improve
system performance while reducing size and cost. The
TGA4548 also has an integrated power detector to support
system diagnostics and other needs.
The TGA4548 is matched to 50Ω with integrated DC
blocking capacitors on both RF I/O ports simplifying system
integration. The frequency coverage and operational
flexibility allows it support satellite communication as well
as point to point data links.
The TGA4548 is 100% DC and RF tested on-wafer to
ensure compliance to electrical specifications.
Lead-free and RoHS compliant.
Evaluation boards are available upon request.
