Intended primarily as a building block for a QRI transmitter, this 20-MHz oscillator delivers a clean 6-V peak-to-peak signal into a 100-ohm load.

The 20-MHz oscillator functions as a critical component in the design of a QRI transmitter, providing a stable frequency source essential for effective signal modulation and transmission. The oscillator is designed to output a clean 6-V peak-to-peak signal, ensuring minimal distortion and high fidelity in the transmitted waveform. This characteristic is vital for maintaining the integrity of the signal, especially in communication systems where clarity and accuracy are paramount.

The load impedance of 100 ohms indicates that the oscillator is optimized for applications that require matching with typical RF circuits or antennas. Proper impedance matching is crucial to maximize power transfer and minimize reflections, which can lead to signal degradation.

In terms of circuit implementation, the oscillator may utilize a combination of active components such as transistors or operational amplifiers, along with passive components like resistors, capacitors, and inductors. The design should include a feedback loop to stabilize the oscillation frequency and ensure consistent performance over varying operating conditions. Additionally, the power supply should be adequately decoupled to prevent noise from affecting the oscillator's output.

Overall, this 20-MHz oscillator serves as a robust and reliable building block for QRI transmitters, contributing to enhanced communication capabilities in various electronic applications.Intended primarily as a building block for a QRI"transmitter, this 20-MHz oscillator delivered a clean 6-V, pk-pk signal into a 100-0 load. 🔗 External reference
