Product Description
The AH118 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
+40.5 dBm OIP3 and +24.7 dBm of compressed 1dB
power. The AH118 is available in a lead-free/green/RoHS-
compliant SOT-89 package. All devices are 100% RF and
DC tested.
The AH118 is targeted for use as a driver amplifier in
wireless infrastructure where high linearity and medium
power is required. Internal biasing allows the AH118 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: 25oC, 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.
