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.
