OEM Balanced Photodetector
The BPD-003 is a small, low noise, DC coupled balanced detector for OEM applications.
The 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 amplifies the output signal to a range of ± 3.5 V. The device is packaged in a small, lightweight shielding box. It has a bandwidth of up to 200 MHz.
