Embodiment Construction

[0025] Please refer to Figure 1A , which is a functional block diagram of a down-frequency device according to an embodiment of the present invention. The signal to be down-converted is transmitted from a connector 170 of the down-frequency device 100 into the down-frequency device 100 . The down-converted signal is delivered from the down-conversion device 100 through the connector 170 . The frequency reduction device 100 uses a first frequency reduction unit 110 and a second frequency reduction unit 120 to perform frequency reduction processing on the signal. Therefore, the frequency of the signal leaving the down-conversion device 100 falls within the measurement range of an external test device E. The frequency reduction device 100 also uses a switching unit 150 to switch signals, and can selectively transfer the unreduced signal directly to the frequency reduction device 100, or pass the signal to the first frequency reduction unit 110 and the second frequency reduction...

Abstract

The invention relates to a frequency reduction device, comprising a first frequency reduction unit and a second frequency reduction unit. The first frequency reduction unit is used for the first frequency reduction of a first oscillation signal, and the second frequency reduction unit is used for the second frequency reduction of the first oscillation signal after the first frequency reduction. The second frequency reduction unit is also used for the frequency reduction of a second oscillation signal.

Description

technical field [0001] The present invention relates to a frequency reduction device, and in particular to a frequency reduction device for an oscillating signal. Background technique [0002] With the development of the electronic industry and the popularization of terminal electronic devices, clients have higher and higher requirements for the quality of the electronic devices. Therefore, how to improve the quality and pass rate of active and passive components in electronic devices has become one of the issues that the industry pays attention to. [0003] Oscillators are indispensable components in electronic devices, and are widely used, such as main boards of personal computers, circuit boards of instruments, communication components of mobile phones, and the like. The oscillating signal output by the oscillator becomes the basis of timing and calculation in electronic devices. Incorrect oscillating signals will slow down the timing, or cause errors in calculations an...
