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.

Notes:
· Via holes are omitted for clarity.

· The microstrip line is weakly co-planer. Ground planes

around it are not necessary for operation of the AH201.

· Adequate heat sinking is required for the device.

Further mounting instructions will be shown in the
"Mounting Configuration" section of this datasheet on
the next revision for the datasheet.

· The pin configuration must be soldered accordingly

(shown on the "Functional Diagram").

· The 900 MHz application circuit board is labeled as
