| AH315 3.3-3.8 GHz WiMAX 2W Driver Amplifier Product Features * 3.3 - 3.8 GHz * 25 dB Gain * EVM <2.5 %@ 25 dBm Pout * Internal Active Bias * +5V Single Supply Voltage * +33 dBm P1dB * RoHS-compliant/Lead-free 5x5 mm QFN SMT package Product Description The AH315 is a high dynamic range broadband driver amplifier in a surface mount package. The two-stage amplifier has 25 dB of gain, while being able to achieve high performance for 3.3-3.8 GHz WiMAX/WiBro applications delivering +25 dBm of linear output power. 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/Green 5x5mm QFN package is surface mountable to allow for low manufacturing costs to the end user. The AH315 is targeted for use in a configuration for the stage amplifier in 802.16 WiMAX basestations where high linearity and medium power is required.
