General Description

The MC10-25110M2 is a mmWave 25-110 GHz, 10dB directional coupler in our connectorized miniature M2-package enabling operation up to 110 GHz. The coupler features excellent directivity, return loss and coupling accuracy. Passive GaAs MMIC technology allows production of smaller constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances result in less unit-to-unit variation than traditional coupler technologies, allowing for accurate simulations using the provided S3P file taken from measured production units. The MC10-25110M2 is available as a 1.0mm connectorized module.

[1] Amplitude Flatness = Median value of ABS(Measured Coupling Power – Average Coupling Factor).

[2] Coupling loss based on average coupling factor.

[3] Excess Insertion Loss = (Input Port to Output Port Insertion Loss) – Coupling Loss.

[4] IL Corrected Directivity = Directivity + Insertion Loss.

Absolute Maximum Ratings

The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If these limits are exceeded, the device may be inoperable or have a reduced lifetime.
