摘要: A programmable directional coupler (504) to detect incident power and possibly reflected is disclosed. The includes first second inductors (512, 522) at least one adjustable capacitor (534, 536). inductor (512) coupled between nodes (Nl, N2), the (522) third fourth (N3, N4) of (504). magnetically has a mutual inductance with inductor. 536) 522). may further include fixed or (538) node among first, second, circuit ground. an resistor (528)
