New GaAs RF PAs offer high linearity & efficiency
At 1W power output, these TriQuint products are ideal for use in Very Small Aperture Terminals (VSATs) and point-to-point as well as point-to-multipoint microwave applications
TriQuint Semiconductor has released two new cost-effective packaged RF power amplifiers.
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 devices have P1dB RF power output of 30dBm (1W) and are housed in cost-efficient 5 x 5mm 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.
The new TGA2527-SM and TGA4539-SM are both in production. Samples and fully-assembled evaluation fixtures are available.
