Samsung patents circuit that tunes signal flow using active components

Patent drawing
Patent drawing from the official filing.

Samsung describes a coupler circuit that splits and manages electrical signals using two active inductors instead of traditional passive parts. These active components adjust the electrical resistance at specific ports to control how the signal moves through the device.

Why it mattersThis design could make signal management circuits smaller and more flexible, which is useful for compact electronics like phones and laptops.

In the filing’s own words

A coupler circuit includes a signal line, a coupled line, a first impedance control circuit and a second impedance control circuit. The signal line is disposed between an input port and an output port. The coupled line is disposed between a coupled port and an isolation port. The first impedance control circuit includes a first active inductor configured without a passive element, is electrically connected to the isolation port and adjusts a first impedance of the isolation port. The second impedance control circuit includes a second active inductor configured without a passive element, is electrically connected to the output port and adjusts a second impedance of the output port.

What exactly they claim (claim 1)

1. A coupler circuit comprising: a signal line between an input port and an output port; a coupled line between a coupled port and an isolation port; a first impedance control circuit including a first active inductor, the first impedance control circuit electrically connected to the isolation port and configured to adjust a first impedance of the isolation port; and a second impedance control circuit including a second active inductor, the second impedance control circuit electrically connected to the output port and configured to adjust a second impedance of the output port, wherein the first active inductor and the second active inductor are free of a passive element.
