Title:
HIGH-FREQUENCY MIXER
Document Type and Number:
WIPO Patent Application WO/2023/175696
Kind Code:
A1
Abstract:
A high-frequency mixer (1) comprises N transistors (2-n), an RF terminal (3), N LO terminals (4-n), an IF terminal (5), a series resonant circuit (6) and an IF matching circuit (8), wherein when the RF frequency of a high-frequency signal is the same as or near the maximum oscillation frequency of the transistors (2-n), the impedance of an output terminal (7) as seen from the IF terminal (5) at the RF frequency is a low impedance and the impedance of the output terminal (7) as seen from the IF terminal (5) at the IF frequency is the combined impedance of the impedance of the series resonant circuit (6) and the impedance of the IF matching circuit (8).
