Abstract: Direct digital-to-RF conversion at the antenna interface offers many exciting opportunities to push the performance envelope of RF transmitters in efficiency, area, signal bandwidth, and ...

Abstract: Low power consumption is a key design requirement for many systems, particularly small sensor platforms. Sub-threshold design allows for very low power operation of digital systems, ...

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, ...

The project aims to create an interesting double-sideband (DSB) radiotelephone transmitter that is powered by the operator’s voice due to the instantaneous energy produced. The project aims to create ...

Ultra-efficient, low-cost RF power amplifiers enable the manufacture of high-performance, low-cost RF power amplifiers in common silicon semiconductors. Architecture enables models of power amplifiers ...

This is very stable, harmonic free, long range fm transmitter circuit which can be used for fm frequencies between 88 and 108 MHz. This can cover 5km range (long distance). It has a very stable ...
