Concept:
Tunnel diodes: These are semiconductor diodes known for their unique property of negative differential resistance within a specific voltage range. This property makes them highly useful for high-frequency applications.
Frequency ranges:
1) Wi-Fi: Typically operates in the 2.4 GHz and 5 GHz bands, falling within the radio frequency (RF) range.
2) Microwave: Covers a wider range from 300 MHz to 300 GHz, overlapping with the upper end of RF and extending into the lower end of the microwave band.
3) Ultraviolet: Lies in the range of 30 kHz to 400 THz, significantly higher than the microwave band.
4) Gamma: Occupies the highest frequency range within the electromagnetic spectrum, starting from 1019 Hz and extending beyond.
Due to their rapid switching capabilities enabled by the negative resistance region, tunnel diodes are most effective in the microwave frequency range. They find applications in oscillators, amplifiers, mixers, and detectors within this specific domain.
