Product Description
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 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.
