 Application: 2.5-2.7 GHz WiMAX Power Amplifier Module The ANADIGICS AWM6423 WiMAX Power Amplifier is a high performance device that delivers exceptional linearity and efficiency at high levels of output power. Designed for portable or mobile applications in the 2.5-2.7 GHz band, it supports the IEEE 802.16e-2005 wireless standard, as well as the IEEE 802.16d-2004 and ETSI EN301-021 standards. The device requires only a nominal +3.3 V supply and a low-current bias input. An increase in supply voltage produces an increase in the maximum linear output power. The integrated detector can be used to monitor output power, and the integrated 25 dB step attenuator enables gain control. No external circuits are required for biasing or RF impedance matching, thus reducing external component costs and facilitating circuit board designs. The AWM6423 is manufactured using advanced InGaP HBT technology that offers state-of-the-art reliability, temperature stability, and ruggedness. It is offered in a 4.5 mm x 4.5 mm x 1.4 mm surface mount module optimized for use in a 50 Ω system. 主要特性: InGaP HBT Technology 30 dB Gain 2.5 % EVM at +22 dBm (+3.3 V Supply) 4 % EVM at +23.5 dBm (+3.3 V Supply) 2.5 % EVM at +23.5 dBm (+4.2 V Supply) 4 % EVM at +25 dBm (+4.2 V Supply) High Efficiency Integrated 25 dB Attenuator Integrated Output Power Detector 50 Ω Matched RF Ports for Reduced Externa Component Count RoHS Compliant 4.5 mm x 4.5 mm x 1.4 mm Surface Mount Module  应用: WiMAX Tranceivers That Support the IEEE 802.16d-2004, IEEE 802.16e-2005, and the ETSI EN301-021 Wireless standards  图1.
