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.
