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.

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 calculate the 3OIP using a 2:1 rule.
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 . (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.

Thermal Specifications
Parameter Rating
Operating Case Temperature -40 to +85° C
Thermal Resistance, Rth (1) 33° C / W
Junction Temperature, Tjc (2) 159° C
Notes:
1. The thermal resistance is referenced from the hottest part of
the junction to the ground slug underneath the device.
2. This corresponds to the typical biasing condition of +5V,
450 mA at an 85° C case temperature. A minimum MTTF
of 1 million hours is achieved for junction temperatures
below 247° C. Tjc is a function of the voltage at pins 6 & 7
and the current applied to pins 6, 7, and 8 and can be
calculated by:
Tjc = Tcase + Rth * Vcc * Icc
Product Marking
The component will be marked with an
“AH215-S8” designator with an alphanumeric
lot code on the top surface of the package.
Tape and reel specifications for this part are
located on the website in the “Application
Notes” section.
ESD / MSL Information
ESD Rating: Class 1B
Value: Passes between 500 and 1000V

MSL Rating: Level 3 at +235° C convection reflow
Standard: JEDEC Standard J-STD-020
Mounting Config. Notes
1. A heatsink underneath the area of the PCB
for the mounted device is strictly required for
proper thermal operation. Damage to the
device can occur without the use of one.
2. Ground / thermal vias are critical for the
proper performance of this device. Vias
should use a .35mm (#80 / .0135”) diameter
drill and have a final plated thru diameter
of .25 mm (.010”).
3. Add as much copper as possible to inner and
outer layers near the part to ensure optimal
thermal performance.
4. Mounting screws can be added near the part
to fasten the board to a heatsink. Ensure that
the ground / thermal via region contacts the
heatsink.
5. Do not put solder mask on the backside of the
PC board in the region where the board
contacts the heatsink.
6. RF trace width depends upon the PC board
material and construction.
7. Use 1 oz. Copper minimum.
8 All dimensions are in millimeters (inches).
Angles are in degrees.
