IXYS subsidiary MwT adds family of GaAs and GaN based high linearity RF PAs to portfolio

IXYS Corp subsidiary MicroWave Technology Inc (MwT) of Fremont, CA, USA has introduced a family of three GaAs and GaN based high linearity RF power amplifiers (WPS-445133-02, WPS-444924-02, and MGA-444940-02) targeted at emerging applications for the 4.4 to 5.1 GHz frequency band, such as telemetry, dedicated high data rate wireless network, point to point wireless communications, and military wireless communications.

• WPS-445133-02 has 2W output power at 1dB gain compression point and 26 dBm linear output power (burst power) at 2.5% EVM (Error-Vector-Magnitude) under the 64 QAM 802.11 digital signal modulation scheme. This multiple-stage power amplifier has 33 dB of gain.

• WPS-444924-02 produces 4W output power at 1dB gain compression point and 29 dBm linear output power at 2% EVM with 10 dB gain.

• As a GaN based high power amplifier that requires 28 Volts on the drain bias, the MGA-444940-02 achieves 10W output power at 2dB gain compression point and 33 dBm linear power at 2.5% EVM with 12 dB gain. The power added efficiency at 2W linear power level for this power amplifier is as high as 20%.

All three power amplifiers are fully matched for both input and output terminals for easy cascade and are packaged in the MwT -02 surface mount package with RoHS compliance, says the firm. The MTBF (mean-Time-Before-Failure) for these microwave/RF power amplifiers is over 100 years at 85 degrees centigrade ambient temperature. Evaluation boards for the power amplifiers in 02 packages are available now.
