The basic laws of thermodynamics ensure that no electronic device can achieve 100% efficiency– although switch-mode power supplies come close (approaching 98%). Unfortunately, anything that generates ...
In just a few years’ time, so many things about wireless communication will be different from the way we know them today. Cellular networks, for example, traditionally made up primarily of larger base ...
Guerrilla RF’s GRF5509 high-performance power amplifier paired with Impinj’s advanced RAIN RFID reader chips to enable increased read range and improved readability of RAIN RFID tags Guerrilla RF, Inc ...
Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...
With the wave of wireless devices proliferating in the world today, there is a corresponding need to perform analysis of RF circuitry. It’s an exciting time for consumers of wireless devices, but it’s ...
Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material, if any, ...
The design and modelling of power amplifiers are central to advancing high-frequency applications, including wireless communication, radar, and satellite systems. In these devices, accurately ...
