TGA2512

射频放大器 5-15 GHz LNA Self Biased

The TriQuint is a wideband low noise amplifier with AGC amplifier for electronic warfare EW, electronic counter measures ECM and radar receiver or driver amplifier applications. Offering high gain 27 dB typical from 5 - 15 GHz, the TGA2512 provides excellent noise performance with typical midband noise figure of 1.4 dB while the balanced topology offers good return loss typically 15dB. The TGA2512 is designed for maximum ease of use. The large input FETs can handle up to 21 dBm input power reliably while the build-in gain control provides 15dB of typical gain control range. The part is also assembled in self-biased mode, using a single +5V supply connection from either side of the chip, or in gate biased mode, allowing the user to control the current for a particular applications. In self-biased mode the TGA2512 offers 6 dBm typical P1dB, while in gate-biased mode the typical P1dB is over 13 dBm. The small size of 2.46 mm² allows ease of compaction into Multi Chip Modules MCMs. The TGA2512 is 100% DC and RF tested on-wafer to ensure performance compliance. The part is lead-free and RoHS compliant.
