The mode of operation of the amplitude-modulated transmitter Class-C output stage is discussed, with particular references to the case where the load impedance varies over the working frequency band; ...

There was this broadcast transmitter I once got asked about. When the transmitter was put in operation, it was said to be powered from a 2-pole power generator that was spinning at 3600 RPM.

Most radio engineers today will recall uncomfortable evenings and cold nights spent in dog houses making antenna impedance measurements, or worse, still trying to balance a laboratory model GR bridge ...

In the first three installments of this series, we discussed whether or not an old transmitter was even worth fixing, followed by some techniques I ve used to repair high-voltage power supplies, ...

With the increased adoption of the JESD204 interface in data converters, it’s become necessary to devote more attention to the performance and optimization of the digital interface—the focus must not ...

The purpose of this article is to explain, in detail, the process involved in building and tuning a high-frequency (HF) RFID antenna, which would operate at 13.56 MHz. Some concepts will be explained ...

Continuous downscaling of integrated circuits has reached a bottleneck. Technologies such as system in a package, multi-chip module and integration of chips on an active or passive interposer can ...
