Medium-Power Amplifier

Mon, 08/30/2004 - 7:45am

Agilent introduces an E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) MMIC (monolithic microwave integrated circuit) medium-power amplifier for use as a driver in wireless fixed-access points/base stations operating at up to 10 GHz. The MGA-425P8 meets WLAN linearity requirements while drawing a low current. The "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. The amplifier is supplied in the compact, industry-standard 2.0 × 2.0 × 0.75 mm 8-pad JEDEC DRP-N LPCC (JEDEC Solid State Technology Association) leadless plastic chip carrier for reduced board space. The amplifier offers the following characteristics at 5.25 GHz, 3 V, 58 mA operation: 13.3 dBm Pout at 5 percent EVM (error vector magnitude), 10.3 percent PAE (power-added efficiency), and 20.3 dBm P1dB (power output at 1 dB gain compression).
