Preliminary Product Information

AH201

Medium Power, High Linearity Amplifier

z

Product Features

@ -45dBc ACPR

Product Description

The AH201 is a 1W driver amplifier that offers

excellent dynamic range in a low cost, 6x6mm

surface mount package. This device can be biased as

low as +9V for lower power applications and as high

as +12V for improved P1dB and OIP3 performance.

The backside metalization allows excellent thermal

dissipation while allowing visible evidence of solder

reflow throughout the bottom of the package on a

SMT board.

Superior thermal design allows the

product an MTBF of over 100 years at a mounting

temperature of +85ºC. All devices are 100% RF &

DC tested.

The product is targeted for use as driver amplifiers for

wireless infrastructure where high linearity and

medium power is required.

Test conditions unless otherwise noted.

1. T = 25ºC, Vdd = 11V, Frequency = 800 MHz, 50 Ohm system.

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.
