Specifications
Product Description
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 an industry standard 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 +5 V supply. This
combination makes the device an excellent candidate for
transceiver line cards in current and next generation
multi-carrier 3G base stations.

Test conditions unless otherwise noted.
1. T = 25oC, Vsupply = +5 V, Frequency = 1900 MHz, 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.
