The PLL transmitter exciter has the functions of providing a stable, low noise, frequency-selectable RF signal and amplify it to a controllable output power sufficient to drive the power amplifier. It ...

At the heart of many amateur radio and other projects lies the VFO, or Variable Frequency Oscillator. Decades ago this would have been a free-running LC tuned circuit, then as technology advanced it ...

Abstract: PLL (Phase Locked Loop) based frequency synthesizers are widely used in the wireless communication field. This paper puts focus on the design and implementation of a 60dB SNR (Signal to ...

The field of radio control has benefited much from the onward march of technology. Where a basic 2-channel setup would once have cost hundreds of dollars, it’s now possible to get a high-end 2.4GHz ...

I recently searched for a digital FM transmitter kit, but most of the ones that I found online were either too expensive or did not have enough flexibility for my future applications. So I decided to ...

This 3d printable shell and Arduino source code will let you build your own RC transmitter for planes, quadcopters, rovers, boats, robots, etc. Hardware needed: Radiomaster zorro-sized AG01 mini; or ...
