ファイ・マイクロテック List of Products and Services

This technology achieves VCO gain nonlinear correction by using the ultra-wideband F/V conversion IC "PH1013FMQFM" to maintain a constant input-output ratio (VCO gain: Volt/Hz) between the control voltage and output frequency of the VCO. Correction is possible regardless of the circuit configuration of the VCO, enabling the realization of a VCO module with high linearity using commercially available VCOs. Additionally, by inserting a frequency divider before the "PH1013FMQFM," further broadening of the linear range is also possible. 【Features】 ■ Achieves VCO gain nonlinear correction ■ Correction is possible regardless of the circuit configuration of the VCO ■ Enables the realization of a VCO module with high linearity using commercially available VCOs ■ Inserting a frequency divider before the PH1013FMQFM allows for further broadening of the linear range *For more details, please refer to the PDF document or feel free to contact us.
