Figure 1: Block Diagram ADA1200 Linear Amplifier ADVANCED PRODUCT INFORMATION - Rev 0.2

FEATURES

  • 50 to 1000 MHz Frequency Range
  • Input IP3: +24 dBm
  • Noise Figure: 2.3 dB
  • Single +5 V Supply
  • Small SOT-89 Package

APPLICATIONS

  • Low Noise Amplifier for CATV Set-Top Boxes
  • CATV Drop Amplifier 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 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

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 specifications.
