Simple high efficiency Colpitts oscillator. In the higher frequency ranges, above 50 MHz, Colpitts oscillators are used because stray circuit capacitance will be in parallel with desired feedback capacitance and not cause undesirable spurious resonances that.... -
I am continuing to add DIY equipment to my home workshop. Audio oscillator is a very useful tool that is needed when we test audio projects. I already have a similar tool but it is just an oscillator without a frequency counter. I decided to use the.... -
An oscillator-only transmitter sounds like the simplest possible means of getting on the radio air ”until you consider the challenges it presents as part of the system that is a transmitting and receiving station: The problem of an adequate.... -
QST`s most recent development ”the Tri-tet oscillator ”has made the single-tube crystal transmitter a really practical affair at last. Practical because it is now possible to work equally well in two ”and, in a pinch, in three ”amateur bands with a single.... -
I did some quick playing with the circuit. It is very close to sustaining oscillation. Changing R2 to 10. 5k will cause it to sustain oscillation. The original authors of the note that you reference are no longer with TI so we cannot consult with them..... -
understanding of the function and sizing of the resistors Rg and Rf for the bubba oscillator circuit described on the application report SLOA060 - march 2011, page 17 figure 18. The oscillator porpuse is to develope a current inverter thru the H-bridge.... -
With the advent of modern radio and radar systems came the need to provide stable harmonic oscillations at particular carrier frequencies to establish the required modulation and mixing conditions. While the carrier frequencies in the early days mostly.... -
Rf = 100 k preset - The slider is set about a quarter of the way round. This is used to control the gain. The gain should be as small as possible consistent with the oscillator starting up reliably. The zener diodes limit the oscillator output by decreasing.... -
