Product Description
Measured Data
The TriQuint TGA2512-SM is a packaged X-
band balanced LNA with AGC amplifier for EW,
ECM, and RADAR receiver or driver amplifier
applications. The TGA2512-SM provides
excellent noise performance with typical
midband NF of 2.3dB, and high gain, 25dB from
4-14GHz
The TGA2512-SM is designed for maximum
ease of use. TGA2512-SM can handle up to
21dBm input power reliably, while the build-in
gain control provides 15dB of typical gain
control range. The part can be used in self-
biased mode, with a single +5V supply
connection, or in gate biased mode, allowing
the user to control the current for a particular
application.
In self-biased mode the TGA2512-SM achieves
6dBm typical P1dB, while in gate-biased mode
the typical P1dB is over 13dBm.
