Product Description

Functional Diagram

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.

1. Test conditions unless otherwise noted: T = 25 ºC, 50 Ω system.

2. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The

suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
