PRODUCT DESCRIPTION
The ADA1200 is a highly linear amplifier developed
to meet the stringent requirements of CA TV systems.
Offered in a low cost SOT-89 package, this GaAs
MESFET design offers low noise and low distortion
over a wide frequency range. The device is ideally
RF Output
/ Bias
RF Input
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.

ELECTRICAL CHARACTERISTICS
T able 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent
damage. Functional operation is not implied under these conditions.
Exposure to absolute ratings for extended periods of time may
adversely affect reliability.
T able 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specifications.
