Title:
ATTENUATOR AND HIGH FREQUENCY DEVICE USING IT
Document Type and Number:
Japanese Patent JP2001044779
Kind Code:
A
Abstract:
To reduce a radiation voltage by an attenuator in a high frequency device used for a television receiver or the like that sends/receives a signal relating to a CATV broadcast.
The attenuator is provided with a diode 10 connected between one terminal and the other terminal, a 1st choke coil 11 connected between the one terminal and ground, and a 2nd choke coil 12 connected between the other terminal and the ground. In order to decrease a loop configured by the circuit components and ground, the 1st choke coil 11 and the 2nd choke coil 12 are placed close to the diode 10 and almost in parallel. Thus, the radiation voltage can be decreased.
