The SA5200 is a dual amplifier with DC to 1200MHz response. Low noise (NF = 3.6dB) makes this part ideal for RF front-ends, and a simple power-down mode saves current for battery operated equipment. Inputs and outputs are matched to 50W.
The enable pin allows the designer the ability to turn the amplifiers on or off, allowing the part to act as an amplifier as well as an attenuator. This is very useful for front-end buffering in receiver applications.
