TriQuint Semiconductor Inc. has released two new cost-effective packaged RF power amplifiers that combine high output with high efficiency, gain and linearity. These solutions are excellent choices for use in Very Small Aperture Terminals (VSATs) and point-to-point as well as point-to-multipoint microwave applications.

The TriQuint TGA2527-SM is very linear and operates from 12.5 to 15.5 GHz, while the TGA4539-SM operates from 28 to 30 GHz. The TGA2527-SM offers very high efficiency, typically 20% greater than competing devices, at its saturated power level (Psat) of 31.5dBm. Both have P1dB RF power output of 30dBm (1W) and are housed in cost-efficient 5x5mm QFN packages; both solutions are RoHS compliant and have onboard power detectors for monitoring purposes. They are designed to be extremely easy to integrate into RF circuits and are highly rugged. The TGA2527-SM can handle an RF input power of 24dBm CW and the TGA4539-SM can handle 22dBm.

         Technical Details:

 

TGA2527-SM

12.5 to 15.5 GHz (Ku-band) RF power amplifier, 30dBm P1dB and 31.5dBm Psat RF output power, 41dBm third order intercept, 25dB gain, 7.5dB noise figure, 6VDC at 650mA, integrated power detector, 5x5 mm QFN package.

TGA4539-SM

28 to 30 GHz (Ka band) 1W RF power amplifier, 30 dBm P1dB and 30.5dBm Psat RF output power, 20dB gain, 6VDC at 420mA, integrated power detector, 5x5 mm QFN package.

The new TGA2527-SM and TGA4539-SM are both in production. Samples and fully-assembled evaluation fixtures are available.
