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.
