Design and Simulation of a Planar Crossed-Dipole Global Navigation Satellite System (GNSS) Antenna in the L1 Frequency Band
… antenna was designed to resonate centered at 1.6 GHz, and then various configurations were investigated and simulated. In an attempt to improve the antenna’s multipath mitigation performance, these various configurations included the addition of concentric rings in various numbers and sizes with …

Techniques for low jitter clock multiplication
… RC filter. The measured performance (for a 1.6 GHz output and 50 MHz reference) demonstrated an overall jitter of 0.93 ps rms, and estimated random and deterministic jitter of 0.68 ps rms and 0.76 ps peak-to-peak, respectively. The proposed MDLL architecture is especially suitable for digital …
