Basic superheterodyne radio transmitter The basic concept of operation is as follows. For the receiver, the signal from the antenna is amplified in the radio frequency (RF) stage. The output of the RF ...

[brmarcum] takes us back to analog building block basics with ... with references to RF, stereo, antennas, and transmitters. [brmarcum] hopes to fill that gap with a simple circuit that modulates ...

The active devices form a two-pole switch that defines either a rectangular voltage or rectangular current waveform at the input of a tuned circuit that includes the load. The load circuit contains a ...

Balancing theoretical background with practical tools and applications, it covers everything from the basic properties ... working in microwave and RF engineering and graduate students looking for a ...

This book, first published in 2004, is an expanded and thoroughly revised edition of Tom Lee's acclaimed guide to the design of gigahertz RF integrated circuits. A new chapter on the principles of ...

We have RF emissions standards to thank ... It’s not surprising to see it kicking the butt of the RTL-SDR, but for basic debugging, simple tools are more than adequate to let you see what ...

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, “SAW ...

The transfer of electromagnetic power wirelessly over a distance was not possible in 19 th century, since the electronic systems like autonomous sensors with ambient RF energy were not available.
