Qorvo's AP603-F is a high dynamic range power amplifier in a lead-free / RoHS-compliant 5 x 6mm power DFN SMT package. The single stage amplifier has excellent backoff linearity, while being able to achieve high performance for 800-2200 MHz applications with up to +38 dBm of compressed 1dB power.

The AP603-F uses a high reliability, high voltage InGaP / GaAs HBT process technology. The device incorporates proprietary bias circuitry to compensate for variations inlinearity and current draw over temperature. The module does not require any negative bias voltage; an internal activebias allows the AP603-F to operate directly off a commonly used high voltage supply (typically +24 to +32V). An added feature allows the quiescent bias to be adjusted externally to meet specific system requirements.

The AP603-F is targeted for use as a pre-driver and driver stage amplifier in wireless infrastructure where high linearity and high efficiency is required. This combination makes the device an excellent candidate for next generation multi-carrier 3G / 4G mobile infrastructure.
