Product Description
Functional Diagram
GND
The AH114 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT is
able to achieve high performance across a broad range with
+41 dBm OIP3 and +24 dBm of compressed 1dB power. It
is housed in a lead-free/green/RoHS-compliant SOT-89
SMT package. All devices are 100% RF and DC tested.

The AH114 is targeted for use as a driver amplifier in
wireless infrastructure where high linearity and medium
power is required. An internal active bias allows the
AH114 to maintain high linearity over temperature and
operate directly off a single +5V supply. This combination
makes the device an excellent candidate for transceiver line
cards in current and next generation multi-carrier 3G base
stations.

1. Test conditions unless otherwise noted: 25 ºC, Vsupply = +5 V, in tuned application circuit.
2. 3OIP measured with two tones at an output power of +11 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
