TGA3503-SM

2 - 30 GHz GaAs Wideband Gain Block

Qorvo's TGA3503-SM is a wideband gain block with adjustable gain control giving the user extra flexibility to fine tune system performance. Operating from 2 to 30GHz, the TGA3503-SM provides 19dBm P1dB and 10dB of small-signal gain with return losses of greater than 12dB.

The TGA3503-SM is fabricated on Qorvo's production TQPHT15 0.15 um GaAs pHEMT process and is offered in a robust, 5x5 mm ceramic air-cavity QFN. With integrated DC blocking caps and fully match to 50 ohms, the TGA3503-SM is easily integrated in both commercial and military system architectures.

Lead-free and RoHS compliant.
