Directional Coupler Specifications


The attenuation of a signal injected into the input port as seen at the coupled port.

Coupling Flatness

The maximum variation in the coupling value over a specified frequency range.

Insertion Loss

The loss of unrecoverable power dissipated within the unit.

Coupling Loss

Power lost from the input signal due solely to the power transferred to the coupling arm of the device.

Mainline Loss

The difference in power between the input signal and the output signal. It is the sum of the Insertion Loss and Coupling Loss.


The level of output power at the coupled port when a signal is injected into the unit in the desired direction minus the level of output power at the coupled port when the same signal is injected in the opposite direction. In a bi-directional unit, it is the difference in output power between the two coupled ports as seen from a constant signal in the same direction


The VSWR (Voltage Standing Wave Ratio) at any given port (with all other ports terminated) defines the degree of mismatch between the input signal and the input port and thus is a measure of the loss of input signal at that port.

RF Couplers from Pandamw can be available in N, SMA, TNC, 2.92mm, 2.4mm,1.85mm connector types. Frequency Range up to 60 GHz and Standard coupling values of 6, 10, 20, 30 and 40 dB are available. While maintaining exceptional coupling flatness, directivity, VSWR, and insertion loss. These precision couplers and tappers for RF are quality manufactured to precise specifications required for accurate coupling at the specified values listed for each product.

Many of our RF Couplers products are RoHS and REACH compliant. We can also customize a model according to your specific requirements. Exceptional customer service and technical support are on hand to support our customers with RF Couplers needs.

Most models available to ship from STOCK – 3 weeks ARO!
