PPT-Directional Couplers EEE 211 Microwave Engineering I

Basic properties of combiners and dividers EEE 211 Microwave Engineering Power DividingCombining It seems a simple task But it is difficult because we want to divider to be matched reciprocal and lossless. However they are highly wavelength dependent A difference in wavelength of only 10nm can cause a significant change in the splitting ratio As a result it is important to specify the exact wavelength at which the fused coupler will be used Finally fu agilentcomfindaccessories Directional Couplers and Bridges Directional Couplers and Bridges Applications Directional couplers are general purpose tools used in RF and microwave signal routing for isolating separating or combining signals They find us All models are available in plugin flatpack surface mount and connectorized SMA BNC Type N TNC option packages All units are designed and built to meet the environmental requirements of MILC15370 and are manufactured to ensure statistical control of Merrimac directional couplers are precision devices carefully designed for monitoring incident and reflected power Merrimac directional couplers are available in four different classes 1 Three port directional couplers 2 Four port bidirectional coup 00 005 2 1 3 4 in mm 1 2 3 4 Output Input Coupling Terminate Directional Input Mark 050 015 025 015 010 040 max 050 005 030 015 010 010 005 LDC18Q Series in mm 1 Main OUT 2 IN 3 Coupled OUT 4 Terminate A Directional Input Mark 16 01 1 2 4 3 09 01 Microwave Engineering .
