Product Features
Product Description
Functional Diagram
The AH314 is a high dynamic range broadband driver
amplifier in a surface mount package. The two-stage
amplifier has 23 dB of gain, while achieving +24 dBm of
linear output power for 2.3–2.9 GHz WiMAX/WiBro
applications.

AH314 uses a high reliability +5V 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
AH314 to operate directly off a commonly available +5V
supply. The RoHS-compliant/Lead-free 5x5mm QFN
package is surface mountable to allow for low
manufacturing costs to the end user.

• Lead-free/RoHS-compliant
5x5 mm QFN SMT package
Applications
• 802.16 WiMAX infrastructure
• WiBro infrastructure
The AH314 is targeted for use in a configuration for the
driver stage amplifier in 802.16 WiMAX or WiBro
basestations where high linearity and medium power is
required.

1. Test conditions unless otherwise noted: 25ºC, +5V Vsupply, in 2.5-2.7GHz tuned application circuit
shown in page 3.
4. Typical parameters reflect performance in a tuned application circuit at +25° C.
2. Using an 802.16-2004 OFDMA, 64QAM-1/2,1024-FFT, 20 symbols, 30 subchannels.
3. This corresponds to the quiescent current or operating current under small-signal conditions with
bias resistor R1=68Ω off pin 1 and R2=150Ω off pin 16.
4. This corresponds to the quiescent current or operating current under small signal conditions into
pins 1, 2, 15 and 17. Pin 1 and 16 is used a reference voltage for the internal biasing circuitry. It is
expected that PIN_VPD1 and PIN_VPD2 will pull 36 mA of current when used with series
resistors (i.e. Total device current typically will be 636 mA).
