Title:
FREQUENCY UP/DOWNCONVERTING ELECTRONIC DEVICE AND MILLIMETER-WAVE LOW PHASE NOISE LOCAL OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2023/277351
Kind Code:
A1
Abstract:
An electronic device for converting frequency and a local oscillator for generating a LO signal are disclosed. The disclosed electronic device may comprise: an IF port which inputs or outputs a first frequency band signal; an RF port which inputs or outputs a second band frequency signal higher than the first frequency band signal; a passive mixer which converts the first frequency band signal to the second frequency band signal or converts the second frequency band signal to the first frequency band signal; a local oscillator which generates a LO signal having one of multiple frequency bands on the basis of a PLL including a tertiary passive filter, and provides the LO signal to the passive mixer; and a bi-directional amplifier which is disposed between the IF port and the passive mixer, and includes a gain equalizer for controlling the gain equality of a signal input to or output from the IF port.
