Wideband radio frequency (RF) receivers allow greatly increased flexibility in radio designs. The wide instantaneous bandwidth allows flexible tuning without changing hardware and the ability to capture multiple channels at widely separated frequencies.
This reference design describes a wideband RF receiver utilizing a 4-GSPS analog-to-digital converter (ADC), with an 8-GHz, DC-coupled, fully differential amplifier front end. The amplifier front end provides signal gain and allows capture of signals down to DC, which is not possible with a balun-coupled input.
