Product Description
The AH118 / ECG099 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 / ECG099 is
available in a lead-free/green/RoHS-compliant SOT-89
package. All devices are 100% RF and DC tested.
The AH118 / ECG099 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.

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.
