ADA1200 Linear Amplifier PRELIMINARY DATA SHEET - Rev 1.3 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 * Low Noise Amplifier for CATV Set-Top Boxes * CATV Drop Amplifier S24 Package SOT-89 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 frequency range. 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.
