Coaxial Dual-Directional Coupler, 100 MHz to 2 GHz
Contact us for pricing and availability.
The Agilent 778D is an economical dual-directional coupler designed for swept measurements in the 100 MHz to 2 GHz range. Its high directivity and mean coupling accuracy of ±0.5 dB makes the Agilent 778D ideal for reflectometer applications. The auxiliary arms track very closely, making this coupler particularly useful for reflectometers driven by sweep oscillators.
