Abstract

We present an experimental demonstration of a 25 GHz optoelectronic oscillator made using an integrated resonant photoreceiver front-end. The front-end consists of an assembly with a photodiode and a co-designed low-noise amplifier that has an input network that provides optimum noise and power matching to the photodiode impedance. Due to the low noise figure and good power matching of the receiver front-end chipset, we measured a phase noise of −118 dBc/Hz @ 10 kHz offset and a floor of −154 dBc/Hz on a 5 dBm output tone.
