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.
