The TriQuint TGA2526 is a compact low noise amplifier (LNA) gain block MMIC with adjustable gain control (AGC). The LNA operates from 2 - 20 GHz and is designed using TriQuint's proven standard 0.15 um power pHEMT production process.

The TGA2526 provides a nominal 20 dBm of output power at 1 dB gain compression with a small signal gain of 17.5 dB. Greater than 30 dB adjustable gain can be achieved using the Vg2 pin. Typical noise figure is 2.5 dB at 12 GHz. Special circuitry on Vd, Vg1 and Vg2 pins provides ESD protection.

The TGA2526 is suitable for a variety of wideband systems such as point-to-point radios, radar warning receivers and electronic counter measures (ECM).

The TGA2526 is 100% DC and RF tested on-wafer to ensure performance compliance. The TGA2526 has a protective surface passivation layer providing environmental robustness. The part is lead-free and RoHS compliant. Evaluation boards are available upon request.
