Product Information
1W High Linearity Amplifier
Product Description
The AH202 is a 1-Watt driver amplifier that offers
excellent dynamic range in a low-cost, lead-free/RoHS-
compliant 6x6 mm 28-pin QFN surface-mount package.
This device provides its optimum P1dB and OIP3
performance when biased at + 11 V; It can also be biased
as low as +9 V for lower power applications.
The backside metalization provides excellent thermal
dissipation while allowing visible evidence of solder reflow
across the bottom of the package on a SMT board.
Superior thermal design allows the product an MTTF of
over 100 years at a mounting temperature of +85º C. All
devices are 100% RF & DC tested.
The product is targeted for use as a driver amplifier for
wireless infrastructure or CATV applications where high
linearity and medium power is required.

1. Test conditions unless otherwise noted: 25ºC, Vdd = 11 V in a 50-
2. 3OIP measured with two tones at an output power of +10 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. IS-95, 9 Channels Forward, Pk/Avg Ratio = 11.5 dB at a .001% probability, ±885 kHz offset, 30
kHz bandwidth, Channel BW = 1.23 MHz.
4. Data reflects performance of a typical AH202 in an application circuit including associated circuit
board and passive component losses.
5. 3GPP W-CDMA, Test Model 1, +32 DPCH, Pk/Avg Ratio = 8.5 dB at a 0.01% probability, ±5
