40 GHz Fiber Coupled Balanced Photodetector / Photoreceiver

The GHBD Balanced Photoreceiver is designed for high-speed analog and digital light detection, offering exceptional performance with a differential gain of approximately 2800 V/W and a bandwidth of up to 40 GHz. It features two waveguide-integrated PIN photodiodes and a limiting amplifier in a compact SMD package with matched fiber lengths. The limiting amplifier delivers a differential output voltage swing of approximately 600 mV. The device achieves excellent electrical and optical phase propagation with a total skew of less than 5 ps between balanced signal paths and 10 ps total skew for all fiber pairs. Independent DC output voltage monitoring is available for OUTN and OUTP, and each amplifier path includes a threshold control at the linear amplification stage to optimize the differential output signal.
