30dB Directional Coupler 380-520MHz


The SP3852-2430-11 4-Port 30dB high directivity directional coupler is typically used for coupling forward and reflected power from a single feeder cable for comparative forward to reflected power level measurements. This directional coupler is designed to provide >60dB of directivity (isolation) between the forward (FWD) and reflected (REV) ports to facilitate a wide power measurement range capability.
