Keysight 778D Dual Directional Coupler, 100MHz - 2GHz

This economic coupler covers frequency spreads of more than 2:1, each centered on one of the VHF/UHF bands. With their high directivity and mean coupling accuracy of ±0.5 dB, these are ideal couplers for reflectometer applications. The close tracking of the auxiliary arms makes these couplers particularly useful for reflectometers driven by sweep oscillators such as the Keysight 8350B with its appropriate plug-in.
