Product Description
The TriQuint TGA4510-SM is a Ka-Band
Packaged Driver Amplifier. The
TGA4510-SM operates from 29-31 GHz
and is designed using TriQuint's proven
standard 0.25-um power pHEMT
production process.
The TGA4510-SM typically provides
17 dBm of saturated output power with
small signal gain of 15 dB.
The TGA4510-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 Base Station
applications.
Evaluation Boards are available upon
request.
Lead-free and RoHS compliant.
