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.
