Agilent introduces an E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) MMIC (monolithic microwave integrated circuit) low noise amplifier for applications in the 0.5 to 6 GHz frequency range, including WLANs, WiMAX point-to-multipoint systems, and cordless phones. The MGA-665P8, from Agilent’s Semiconductor Products Group, is designed for applications operating in the 5 GHz UNII (unlicensed national information infrastructure) band, such as IEEE 802.11a WLANs. It also offers good performance for IEEE 802.11b and 802.11g WLANs operating in the 2.4 GHz license-free ISM (industrial, scientific, and medical) band and WiMAX in the 3.5 GHz licensed international frequency range. The device is supplied with its output matched to 50Ω and input partially matched. At 5.25 GHz, the amplifier features a 1.45 dB noise figure combined with 16 dB gain and 18.1 dBm OIP3 (output third-order intercept point). At 2.4 GHz, the amplifier features 1.2 dB NF, 18.4 dB gain and 19 dBm OIP3 (all performance typical at 3 V, 20.5 mA bias).
