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.
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.
