Product Description
The AH2 is a general purpose, high dynamic range amplifier targeting cable TV markets. The bination 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 Ga As 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/Ro HS-pliant SOT-89 package. All devices are 100% RF and DC tested.
