The BPD-003 combines an optical head and a post-amplification board with an 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 230 MHz.
