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 for various
narrowband-tuned application circuits with up to +46
dBm OIP3 and +31.5 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.

4. Typical parameters reflect performance in a tuned application circuit at+25° C.
1. Test conditions unless otherwise noted: T = 25ºC, Vsupply = +5 V, Frequency = 2140 MHz in a
tuned 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 cal ulate the 3OIP using a 2:1 rule.
c
3. This corresponds to the quiescent current or operating current under small-signal conditions into
pins 6, 7, and 8. It is expected that the current can increase by an additional 90 mA at P1dB. Pin 1
is used as a reference voltage for the internal biasing circuitry. It is expected that Pin 1 will pull
10.8 mA of current when used with a series bias resistor of R1=51
Ω.
(ie. total device current
typically will be 461 mA.)

Notes:
The gain for the unmatched device in 50 ohm system is shown as the trace in black color. For a tuned circuit for a particular frequency,
it is expected that actual gain will be higher, up to the maximum stable gain. The maximum stable gain is shown in the dashed red line.
The impedance loss plots are shown from 0.05 – 5.05 GHz, with markers placed in 0.5 GHz increments.
