High Dynamic Range 1.8W 28V HBT Amplifier
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.
Functional Diagram
ACLR1 (dBc)
The AP601 uses a high reliability, high voltage
InGaP/GaAs HBT process technology.
The device
Internal Active Bias
incorporates proprietary bias circuitry to compensate for
Internal Temp Compensation
variations in linearity and current draw over temperature.
Capable of handling 7:1 VSWR @
The module does not require any negative bias voltage; an
internal active bias allows the AP601 to operate directly off
28 Vcc, 2.14 GHz, 1W CW Pout
a commonly used high voltage supply (typically +24 to
+32V). An added feature allows the quiescent bias to be
Lead-free/RoHS-compliant
adjusted externally to meet specific system requirements.
5x6 mm power DFN package
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.

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 marked red line.
The impedance plots are shown from 50 – 3000 MHz, with markers placed at 0.5 – 3.0 GHz in 0.5 GHz increments.

= 2.45, Microstrip line details: width = .042”, spacing = .050”
Notes:
1. Please note that for reliable operation, the evaluation board will have to be mounted to a much larger
heat sink during operation and in laboratory environments to dissipate the power consumed by the
device. The use of a convection fan is also recommended in laboratory environments.
2. The area around the module underneath the PCB should not contain any soldermask in order to
maintain good RF grounding.
3. For proper and safe operation in the laboratory, the power-on sequencing is recommended.
Evaluation Board Bias Procedure
Following bias procedure is recommended to ensure proper functionality of AP601 in a laboratory environment. The sequencing is not
required in the final system application.

Attach input and output loads onto the evaluation board.
Turn on power supply Vcc = +28V.
Turn on power supply Vbias = +5V. At this point, the only current drawn by the device is leakage current (< 25μA).
Turn on power supply Vpd = +5V. Power supply Vcc should now be drawing typical Icq = 40 mA.
Turn on RF power.
Turn off RF power.
Turn off power supply Vpd = +5V.
Turn off power supply Vbias = +5V.
Turn off power supply Vcc = +28V.
Icq can be adjusted with the resistor R2 from the Vpd (+5V) supply and the PIN_VPD (pin14) of the amplifier. Increasing R2
results in a lower Icq. Icq should not be increased above 80mA.
Vpd is used as a reference for the internal active bias circuitry. It can be used to turn on/off the amplifier. Ipd depends on the Icq
quiescent current setting. Ipd can be up to 2mA at a quiescent current setting of 40mA.
Vbias should be maintained fixed at +5V. Ibias will change based on RF input power level. It can be up to 2mA on the AP601.
