AP561

0.7-2.9 GHz WiMAX 8W Power Amplifier

Product Features

5x6 mm power DFN package

Applications

Product Description

The AP561 is a high dynamic range broadband power

amplifier in a surface mount package. The single-stage

amplifier has 13 dB Gain, while being able to achieve high

performance for 0.7–2.9 GHz 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.

Notes:

1. Test conditions unless otherwise noted: T = 25ºC, Vpd = +5V, Vcc = +12, Icq = 300mA at Pout = +30

dBm and f = 2.6 GHz.

2. Using an 802.16-2004 OFDMA, 64QAM-1/2,1024-FFT, 20 symbols, 30 subchannels signal, 9.5

dB PAR @ 0.01%.

3. Switching speed: 50% TTL to 100/0% RF.Vpd used for device power down (low=RF off).

4. Vpd relates to Iref as shown in Table 1 on Page 12.
