Pasternack Directional Couplers
Directional couplers are passive devices that couple part of the transmission power in a transmission line. These directional RF couplers change by a known amount out through another port. A typical RF directional coupler often uses two transmission lines set close enough together such that energy passing through one is coupled to the other.
Pasternack directional RF couplers provide the bandwidth, high directivity and higher power at up to 60W that designers need for their most demanding applications.
