Linear Amplifier

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.

Please note: ADA1200 is being discontinued and is not recommended for new designs. SKY65452-92LF, SKY65450-92LF or ADA10001.
