Product Description
The AP561 is a high dynamic range broadband power amplifier in a surface mount package. The single-stage amplifier has 13.8 dB gain, while being able to achieve high performance for 2.3–2.9 GHz WiMAX applications with up to 39 dBm of compressed 1dB power.
The AP561 uses a high reliability +12V 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 AP561 to operate directly off a commonly used +12V supply and has the added feature of a +5V power down control pin. RoHS-compliant 5x6mm DFN package is surface mountable to allow for low manufacturing costs to the end user.
The AP561 is targeted for use in a balanced or single ended configuration for WiMAX or WiBro applications where high linearity and high power is required.
