The AP562 is a high dynamic range broadband power
amplifier in a surface mount package. The single-stage
amplifier has 11.5 dB gain, while being able to achieve
high performance for 3.3–3.8 GHz WiMAX applications
with up to 39.4 dBm of compressed 1dB power.

The AP562 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
AP562 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 AP562 is targeted for use in a balanced or single ended
configuration for WiMAX applications where high linearity
and high power is required.

Evaluation Board Bias Procedure

Following bias procedure is recommended to ensure proper functionality of AP562 in a laboratory environment. The sequencing is not
required in the final system application.

Turn-on Sequence:

1. Attach input and output loads onto the evaluation board.

2. Turn on power supply Vcc = +12V.

3. Turn on power supply Vpd = +5V.

4. Turn on RF power.

Turn-off Sequence:

Notes:

The gain for the unmatched device in 50 ohm system is shown as the trace in black color. For a tuned circuit for a particular frequency, it is expected that
actual gain will be higher, up to the maximum stable gain. The maximum stable gain is shown in the red line.
