AP601

High Dynamic Range 1.8W 28V HBT Amplifier

Product Features

28 Vcc, 2.14 GHz, 1W CW Pout

5x6 mm power DFN package

Applications

Product Description

The AP601 is a high dynamic range power amplifier in a

lead-free/RoHS-compliant 5x6mm power DFN SMT

package. The single stage amplifier has 13.5 dB gain, while

being able to achieve high performance for 800-2400 MHz

applications with up to +32.5 dBm of compressed 1dB power.

The AP601 uses a high reliability, high voltage

InGaP/GaAs HBT process technology.

The device

incorporates proprietary bias circuitry to compensate for

variations in linearity and current draw over temperature.

The module does not require any negative bias voltage; an

internal active bias allows the AP601 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 AP601 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 mobile infrastructure.

Notes:

1. The reference designs shown in this datasheet have the device optimized for WCDMA ACLR

performance at +25

° C. Biasing for the amplifier is suggested at Vcc = +28V and Icq = 40 mA to

achieve the best tradeoff in terms of efficiency and linearity. Increasing Icq will improve upon the

device linearity (IMD3 and ACLR), but will decrease the efficiency performance slightly. More

information is given in the other parts of this datasheet.

2. The AP601 evaluation board has been tested for ruggedness to be capable of handling:

7:1 VSWR @ +28 Vcc, 2140 MHz, 1W CW Pout,

5:1 VSWR @ +30 Vcc, 2140 MHz, 1W CW Pout,

3:1 VSWR @ +32 Vcc, 2140 MHz, 1W CW Pout.
