EWING, N.J. -- Discovery Semiconductors, Inc. advances its narrowband optical receiver for RF-over-Fiber applications covering a frequency range of 54 to 67 GHz. This product can generate linear RF output power up to -10 dBm, or 200 mV peak-to-peak output voltage. With an operating wavelength at both 1310 nm as well as 1550 nm wavelengths, it has 20 dB power gain, and a power dissipation of less than 200 mW. It also exhibits low amplitude ripple in the device passband.

This highly linear narrowband optical receiver will provide better gain, output voltage, as well as phase stability for photonics links. It will serve various V-band RF-over-Fiber market segments that improve wireless performance in applications including wireless systems, distribution of microwave RF carriers, and antenna remoting.

Dr. Christina Lim, Professor at the Electrical and Electronic Engineering Department, University of Melbourne commented, “This product is an excellent integrated optical-to-electrical converter with sufficient gain suitable for radio-over-fiber applications based on the 60 GHz band. With this Discovery photo-receiver we have been able to achieve error-free reception of 1.8 Gb/s BPSK (limited by our phase-locked loop) at 60 GHz with a received optical power of -9 dBm. It opens the door for interesting antenna remoting applications over this band of rising popularity supported by optical fiber feeder networks.”
