Product Description
The TriQuint TGA4509-SM is a
Ka-Band Packaged 1W Power Amplifier.
The TGA4509-SM operates from 28-31
GHz and is designed using TriQuint’s
proven standard 0.25 um power pHEMT
production process.
The TGA4509-SM typically provides 30
dBm of output power at 1 dB gain
compression with small signal gain of 19
dB.
The TGA4509-SM is available in a low-
cost, surface mount 4x4 QFN style
package and is ideally suited for Ka-
band VSAT Ground Terminal, Point-to-
Point Radio and Point-to-Multipoint
applications.
Evaluation Boards are available upon
request.
Lead-free and RoHS compliant.
