AH2

High Dynamic Range Amplifier

Product Information

Product Features

Product Description

Functional Diagram

GND

The AH2 is a general purpose, high dynamic range

amplifier targeting cable TV markets. The combination of

gain flatness, high linearity and bandwidth make it ideal for

CATV distribution, cable modem and laser diode driver

applications. The AH2 is designed for 75 ohm systems and

can operate directly from a +5 Volt DC regulator. The

device is manufactured using reliable GaAs MESFET

technology and boasts an MTBF of >100 years at a

mounting temperature of +85 °C. It is available in the

environmentally-friendly lead-free/green/RoHS-compliant

SOT-89 package. All devices are 100% RF and DC tested.
