Hobbs balanced detector
NettetThe BPD-003 combines an optical head and a post-amplification board with an SMA or SMB RF output connector. The optical head consists of two input fibers aligned with a pair of balanced photodetectors followed immediately by an integrated low noise transimpedance amplifier (TIA). The post-amplification circuit further conditions and … NettetNirvana photoreceivers operate in signal mode, balanced mode, or auto-balanced mode. The output of the photodetector (A) can be expressed as A= (IS – g x IR) x Rf. Here, IS the signal photodiode current, IR is the …
