Abstract
The objective of this proposal is to perform a system study to demonstrate the benefits of using a tunable photonic Hybrid Photonic Receiver filter to reduce intermodulation distortion effects on wideband communication receivers. A traditional Radio Frequency (RF) receiver digitizes high frequency (HF), very high frequency (VHF), and ultra-high frequency (UHF) spectrums simultaneously and then samples the spectrum of interest to baseband for final processing. In a dense signal environment or in the presence of a strong signal in the communication band, the dynamic range of the detector is limited by generated non-linearities, such as 2nd and 3rd order harmonics and intermodulation distortion produced in the Analog-to-Digital (ADC). GenXComm has built a platform technology that allows for creating wide band, tunable pre-select filter with high Q. We propose to use this technology in building chip-scale filters as a drop-in solution that replaces the pre-selection filter and suppresses all undesired signals, both in and out of band.
