Product Description
The AH115 / ECP050G is a high dynamic range driver
amplifier in a low-cost surface mount package.
The
InGaP/GaAs HBT is able to achieve high performance for
various narrow-band tuned application circuits with up to
+44 dBm OIP3 and +28.5 dBm of compressed 1-dB power.
All devices are 100% RF and DC tested. The AH115 /
ECP050G is available in lead-free/green/RoHS-compliant
SOIC-8 package.
The product is targeted for use as driver amplifiers for
wireless infrastructure where high linearity and medium
power is required. The internal active bias allows the
AH115 / ECP050G to maintain high linearity over
temperature and operate directly off a +5 V supply. This
combination makes the device an excellent fit for
transceiver line cards and power amplifiers in current and
next generation multi-carrier 3G base stations.

1. Test conditions unless otherwise noted. 25C, 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.
3. This corresponds to the quiescent current or operating current under small-signal conditions. It is
expected that the current can increase up to 300mA at P1dB.
