PIN diodes, as inertial nonlinear elements, are widely used in transceiver equipment of various frequency ranges as limiters, attenuators and phase shifters. Also, with their help, it is possible to implement double-sided switching elements used, amo

International audience; We identify five types of antenna tuner control scheme, which are suitable for a wireless transmitter using a single antenna. Four of them use a sensing unit measuring electrical variables either at the radio port or at the an

ESD discharges to antennas can damage the RF front end. In particular, antennas with highly inductive ground connections allow large ESD-induced voltages at their RF terminals. This work investigates the ESD properties of an RF switch used as an ante

2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting.
Synchronously tuning an electrically small antenna at the symbol rate of a frequency shift keyed (FSK) modulation has been shown to efficiently increase the throughput of the transmitter. A major challenge for realizing synchronous antenna tuners is
