Specifications
Product Description
The AH22 is a high dynamic range amplifier tar-
geting cable TV markets. A combination of gain
flatness, high linearity and bandwidth make it
ideal for CATV distribution, cable modem and
laser diode driver applications. The device is
designed for 75 Ω systems and packaged for
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 AH22 measured with external matching circuits.
2. OIP3 measured with 2 tones at an output power of 8 dBm/tone separated by 10 MHz. The suppression on the largest IM3 product is used to calculate OIP3 using a 2:1 slope rule.
