General Description

Pin Configuration

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 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 AH315 is targeted for use in a configuration for the

driver stage amplifier in 802.16 WiMAX base stations

where high linearity and medium power is required.
