Single Positive Supply (+5 V)
SOIC-8 SMT Package
Product Description
The AH215 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT
is able to achieve superior performance over a broad
frequency range with +46 dBm OIP3 and +31 dBm of
compressed 1-dB power. The part is housed in an
industry standard SOIC-8 SMT package. All devices are
100% RF and dc tested.
The product is targeted for use as driver amplifier for
various current and next generation wireless technologies
such as GPRS, GSM, CDMA, W-CDMA, and UMTS,
where high linearity and high power is required.
The
internal active bias allows the AH215 to maintain high
linearity over temperature and operate directly off a +5 V
supply.

Test conditions unless otherwise noted.
1. T = 25C, Vsupply = +5 V, Frequency = 2140 MHz, in recommended application circuit.
2. 3OIP measured with two tones at an output power of +15 dBm/tone separated by 1 MHz.
The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
