Linear Amplier
PRELIMINARY DATA SHEET - Rev 1.4
FEATURES
• 12 dB Gain
• 50 to 1000 MHz Frequency Range
• Noise Figure: 2.3 dB
• Single +5 V Supply
• Small SOT-89 Package
• RoHS Compliant/Lead-free
APPLICATIONS

PRODUCT DESCRIPTION
The ADA1200 is a highly linear amplier 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 frequency range. The device is ideally
RF Output
/ Bias
RF Input
suited for applications as a Low Noise Amplier in
CATV Set-Top Boxes, and as a Drop Amplier in CATV
distribution systems. The ADA1200 requires a single
+5 V supply, and typically consumes 400 mW of power.

ELECTRICAL CHARACTERISTICS
Table 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.
Table 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
specications.
