AH11
Product Description
The AH11 is a high power linear amplifier
for use in digital communications systems.
It combines low noise figure and high
intercept point into a low cost SMT
solution. This device extends the linear
efficiency advantages of WJ’s AH1 to higher
power levels. The device packaging allows for
both balanced and push-pull operation.
A mature and reliable GaAs MESFET
technology is employed to maximize
linearity at low power dissipation. The
package is a thermally enhanced SOIC-8
and all devices are 100% RF tested.

1.Typical specifications reflect AH11 measured with external matching circuits.
2. OIP3 measured with 2 tones at an output power of 8 dBm/tone balanced, 11 dBm/tone push-pull, separated by 10 MHz.
The suppression on the largest IM3 product is used to calculate OIP3 using a 2:1 slope rule.
3. Balun loss affects noise figure.
