PRODUCT DESCRIPTION
The ADA1200 is a highly linear amplifier developed
to meet the stringent requirements of CATV systems.
Offered in a low cost SOT-89 package, this GaAs
MESFET design offers low noise and low distortion
over a wide range of frequencies. The device is ideally
suited for applications as a Low Noise Amplifier in
CATV Set-Top Boxes, and as a Drop Amplifier in
CATV distribution systems. The ADA1200 requires
a single +5 V supply, and typically consumes 400
mW of power.
