11. Operating frequencies of electronic ballasts are selected to avoid interference with infrared remote controls.12. However, because of high switching losses, typical operating frequency is up to 500 Hz. 13. Proposed operating frequencies are around 2.4 GHz in digital modes. 14. For typical acoustic-based microdevices, the operating frequency ranges from ~ kHz to ~ MHz. 15. Different ceramic materials have differing losses over the temperature range and the operating frequency . 16. The operating frequency was 190 to 195 MHz with a wavelength of 1.5 metres. 17. Silicon-based power transistors are reaching limits of operating frequency , breakdown voltage, and power density. 18. Frequency modulation is most commonly generated at the operating frequency with the required deviation. 19. This influences the capacitance value of tantalum capacitors, which depend on operating frequency and temperature. 20. For Core i7-920XM, normal operating frequency is 2.0 GHz.
