Abstract
A frequency reference device that includes a frequency reference generation unit to generate a frequency reference signal based on an absorption line of a gas.
Claims26
A frequency reference device, comprising:
- a frequency reference generation unit to generate a frequency reference signal based on an absorption line of a gas.
A method of generating a reference frequency, comprising:
- receiving a radio frequency (RF) signal transmitted through a gas absorption cell containing a gas;
- detecting an absorption line of the gas with the RF signal;
- and
- generating a reference frequency based on the frequency of the absorption line.
