IXYS ships WiMax power amplifier modules

IXYS Corp subsidiary MicroWave Technology Inc (MwT) of Fremont, CA, USA, which manufactures GaAs-based devices, MMICs, and amplifier modules for microwave and wireless communications, has started shipping its WPS-545922-02 high-linearity WiMax power amplifier module (PAM) to a first-tier telecom system company in production volume for high-data-rate wireless communication applications, including 4.9–5.9GHz OFDM (orthogonal frequency division multiplex) digital radio.

The WPS-545922-02 is a highly integrated PA module with fully matched input and output terminals (no external matching elements are required). It is a member of the WPS (Wireless Power Series) PAM product family (targeted at 802.16 WiMax, 802.11 wireless LAN and other high-data-rate wireless radio link applications), which includes high-linearity PAMs operating in the 2.5, 3.5 and 5.9 GHz frequency bands with up to 5W peak power and up to 1W linear average output power at 2% EVM (error vector magnitude) under 64QAM digital modulation scheme, which enables radio systems to achieve the highest data rates with minimum power consumption, the firm says.

MwT has already released a family of eight high-linearity power amplifiers (PA) for WiFi (802.11) and WiMax (802.16d/e) standards for all three frequency bands: 2.4–2.7GHz, 3.3–3.7GHz, and 4.9–5.9GHz.
