These are the grandchildren of the old mini circuits modules that were popular among hams and RF experimenters decades ago. However, these are cheap, simple, and tiny. You only need a handful of ...

Some prior experience with Arduino is recommended. Simple RF Circuit Design Michael Ossmann will show specific examples from his own designs including Ubertooth One, HackRF One, and YARD Stick One.

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 ...

A design of voltage doubler circuit has been studied in context of electromagnetic ... Dickson voltage multiplier for radio frequency (RF) energy harvesting, shown in Fig.1-a, is simple and has an ...
