TGA2525

The TriQuint TGA2525 is a compact low noise amplifier (LNA) gain block MMIC with adjustable gain control (AGC). The LNA operates from 2 to 18 GHz and is designed using TriQuint's proven standard 0.15 um power pHEMT production process. The TGA2525 provides a nominal 18 dBm of output power at 1 dB gain compression with a small signal gain of 17 dB. Greater than 30 dB adjustable gain can be achieved using Vg2 pin. Typical noise figure is 2 dB at 8 GHz. Special circuitry on both Vg1 and Vg2 pins provides ESD protection. The TGA2525 is suitable for a variety of wideband systems such as point-to-point radios, radar warning receivers and electronic counter measures (ECM). The TGA2525 is 100% DC and RF tested on-wafer to ensure performance compliance. The TGA2525 has a protective surface passivation layer providing environmental robustness. The part is lead-Free and RoHS compliant. Evaluation boards are available upon request.
