The two-stage amplifier has 25 dB of gain, while achieving +25 dBm of linear output power for 3.3-3.8 GHz WiMAX/WiBro applications. AH315 uses a high reliability +5V InGaP/GaAs HBT process technology. The device incorporates proprietary bias circuitry to compensate for variations in linearity and current draw over temperature. The device does not require any negative bias voltage; an internal active bias allows the AH315 to operate directly off a commonly used single +5V supply. The RoHS-compliant/Lead-free 5x5mm QFN package is surface mountable to allow for low manufacturing costs to the end user.

The recommended circuit configurations shown previously in this datasheet have the device operating with a 600 mA as the quiescent current (ICQ). This biasing level represents a tradeoff in terms of EVM and efficiency. Lowering ICQ will improve upon the efficiency of the device, but degrade the EVM performance. Measured data shown in the plots below represents the AH315 measured and configured for 3.5 GHz applications. It is expected that variation of the bias current for other frequency applications will produce similar performance results.
