Features
5 MHz-200 MHz Bandwidth Supports the
Return Path Application. Excellent RF Frequency, High RF Output. Low Noise (<1.0 pA/√Hz typ.) Low Power Dissipation (0.5 W max). RoHS Compliant Internal Prorietary Impedance Match Circuitry (75Ω) Robust Small Package with Single-Mode Fiber Pigtail and Connector Options Wide Operating Case Temp Range, -40O to + 85OC The 7820R RFoG return path optical receiver is a single-mode fiber pigtailed module featuring a low-noise, impedance-matched broadband photodiode and RF amplification. The device receives optical analog and/or digital signals for a range of return path, and delivers the corresponding RF electrical output. The 7820R exhibits excellent noise performance with values well above standards over the entire 200MHz bandwidth and case temperature specifications (-40°C to +85°C). Moreover, the proprietary impedance-match circuitry between the photodetector and RF amplification stages resolves a number of OEM design obstacles. The device’s noise performance is typically less than 0.75pA/√Hz for the 85MHz version and 1pA/√Hz for the 200MHz version. The 7820R RFoG return path optical receiver can be used in the optical wavelength range from 1260nm – 1620nm applications. The 7820R is compliant with all criteria of the Restriction of the Use of Hazardous Substances in Electrical and Electronic Equipment (RoHS) guidelines 2002/95/EC.
