70 GHz High-speed Photodetector


High-Speed Detectors and Receivers

The XPDV3120R comprises an optimized 70GHz waveguide-integrated photodiode, which shows an extremely flat frequency response, both in power and in phase. II-VI‘s on-chip integrated bias network with an optimized RF-design in particular ensures an undisturbed frequency response from DC to the 3dB cut-off frequency and saves cost for an external bias-tee. The hermetic module is especially designed for optimal RF-performance; therefore, the pulse response reveals virtually no ringing. It is best suited for Test & Measurement or Microwave photonics applications up to 60GHz.

A further advantage of the waveguide structure is the unbeatable high power behavior. The photodetector shows a linear response up to an optical input power of 10dBm. An output voltage swing of more than 0.5Vpp can be achieved for short pulses, without any degradation of the pulse response.
