Qorvo TGA4548-SM
TGA4548-SM
® 17 20 GHz 10 W GaN Power Amplifier
Product Overview
Qorvo’s TGA4548-SM is a high frequency, high power
MMIC amplifier fabricated on Qorvo’s production 0.15um
GaN on SiC process (QGaN15). The TGA4548-SM
operates from 17 20 GHz and typically provides > 10 W
saturated output power with power-added efficiency of 25%
and large-signal gain of 18 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-SM also has an
integrated power detector to support system diagnostics
and other needs.
The TGA4548-SM is offered in a small 5x5.5 mm surface
mount package, matched to 50Ω and has integrated DC
blocking capacitors on both RF ports allowing for simple
system integration. The frequency coverage and
operational flexibility allows it support satellite
communication as well as point to point data links.
The TGA4548-SM is 100% DC and RF tested to ensure
compliance to electrical specifications.
Lead-free and RoHS compliant.
