Title:
MULTIPLEXER
Document Type and Number:
WIPO Patent Application WO/2021/260927
Kind Code:
A1
Abstract:
A multiplexer (4) is configured by: a distribution-type amplifier (1a) into which a signal (Vin1) is input and for which an impedance is matched to 50 Ω; a distribution-type amplifier (2a) into which a signal (Vin2) is input and for which an impedance is matched to 50 Ω; and a passive multiplexer (3a) which multiplexes output signals of the distribution-type amplifiers (1a, 2a). The passive multiplexer (3a) is configured by resistors (R30-R32). The resistance value of the resistors (R30-R32) is 16.7 Ω.
