| AH314 Product Features * 2.3 - 2.9 GHz * 23 dB Gain * EVM <2.5 %@ 24 dBm Pout * Internal Active Bias * +5V Single Supply Voltage * +33 dBm P1dB * Lead-free/RoHS-compliant 5x5 mm QFN SMT package 2.3-2.9 GHz WiMAX 2W Driver Amplifier Product Description The AH314 is a high dynamic range broadband driver amplifier in a surface mount package. The two-stage amplifier has 23 dB of gain, while achieving +24 dBm of linear output power for 2.3-2.9 GHz WiMAX/WiBro applications. AH314 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 AH314 to operate directly off a commonly available +5V supply. The RoHS-compliant/Lead-free 5x5mm QFN package is surface mountable to allow for low manufacturing costs to the end user. The AH314 is targeted for use in a configuration for the driver stage amplifier in 802.16 WiMAX or WiBro basestations where high linearity and medium power is required.

R1 sets the quiescent current in the output stage, while R2 sets the quiescent current in the input stage. 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. Raising ICQ will improve the EVM performance, but degrade the efficiency of the device. Measured data shown in the plots below represents the AH314 measured and configured for 2.6 GHz applications. It is expected that variation of the bias current for other frequency applications will produce similar performance results.
