18GHz Microwave Photonics Receiver


LD-PD manufactures a wide range of component photoreceivers with wide bandwidths up to 18 GHz. The MPR0018 Microwave Photonics Receiver extends link response to greater than 18 GHz via direct optical-to-analog RF conversion for signal remoting, communications, radar and information processing applications.

The unit consists of a high speed InGaAs PIN photodiode coupled to the RF output connector. It includes internal bias decoupling and can operate over a wide range of supply voltages (+3 to +15V). The detector response covers 1300 to 1600 nm. It is pigtailed with 900µm jacketed, single mode (ITU-T G.652.D compliant) fiber and can be terminated with a variety of optical connector options.The entire unit is contained in a sealed housing and weighs less than 25 grams.
