AH2
High Dynamic Range CATV Amplifier
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 MTTF of >100 years at a mounting temperature of
85°C. All devices are 100% RF and DC tested.

Parameters reflect performance of a packaged device in a 75
system at 25°C, Vdd = 5.0V, and 800 MHz.
2. OIP3 measured with 2 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 OIP3 using a 2:1 slope rule.
3. The maximum junction temperature ensures a minimum MTTF rating of 1 million hours of usage
at a tab temperature of +85°C. The MTTF plot and more information is located in the
WJ Application Note “AH2 Temperature Effects on Reliability” for more information.
