Agilent Technologies Inc. has introduced an E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) MMIC (monolithic microwave integrated circuit) medium-power amplifier, optimised for use as a driver in wireless fixed-access points/base stations operating at up to 10 HGz. The MGA-425P8 meets wireless local area network (WLAN) linearity requirements while drawing one of the lowest currents in the market.

A ‘smart bias' feature allows the designer to use the device in several circuit positions, tailoring the gain, linearity and current consumption to suit each position. On-chip bias circuitry allows operation from a single 3.3V power supply.
