Coupling : 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.
Directivity : 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
VSWR : 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.
Panda Microwave offers Directional Coupler, standard coupling values of 6, 10, 20, 30, 40dB, frequency range up to 70 GHz, average power 1 to 50 watts. It is available in N, SMA, TNC, 2.92mm, 2.4mm, connector type. Broadband Directional coupler and Bi-Directional coupler (dual directional coupler) 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.
