Specifications
The AH201 is a 1W driver amplifier that offers
excellent dynamic range in a low cost, 6x6m
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 solde
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 fo
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.

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 accordingl
(shown on the “Functional Diagram”).
• The 900 MHz application circuit board is labeled as
AH201-PCB-900.
• The 1900 MHz and 2200 MHz application circuit board
is labeled as AH201-PCB-1900.
