AP601
High Dynamic Range 1.8W 28V HBT Amplifier
Product Features
Product Description
Functional Diagram
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.
• 800 – 2400 MHz
• +32.5 dBm P1dB
• -51 dBc ACLR @ ¼W PAVG
• -55 dBc IMD3 @ ¼W PEP
• 17% Efficiency @ ¼W PAVG
• Internal Active Bias
The AP601 uses
InGaP/GaAs HBT process technology.
a
high reliability, high voltage
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.
• Internal Temp Compensation
• Capable of handling 7:1 VSWR @

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.
