Chip type directional coupler
摘要:
Disclosed herein is a chip type directional coupler comprising a laminated structure having two stripline electrode substrates, each provided with a quarter-wavelength stripline electrode portion meandered on one major surface thereof, which are so stacked as to electromagnetically couple the stripline electrodes with each other and two ground electrode substrates, provided with ground electrodes, which are stacked to hold the two stripline electrode substrates, and a plurality of external electrodes formed on side surfaces of the laminated structure. Respective end portions of the stripline electrodes and the ground electrodes are electrically connected to different ones of the external electrodes respectively.
