Abstract
An apparatus includes a tunable diplexer; first, second and third radio nodes; and path selection circuitry. The tunable diplexer includes a dedicated port, at least a first signal port and a second signal port, and control inputs configured to change at least one of frequency characteristics and phase characteristics of the tunable diplexer. The path selection circuitry is configurable to select between a first signal pathway between the third radio node and the first signal port and a second signal pathway between the third radio node and the second signal port. The tunable diplexer may have control signals inputs to select between the first and second signal pathways based on an expected interference scenario between radio signals at the first and second signal ports, and the control signals may change frequency characteristics and/or phase characteristics of at least one of the signal ports based on an operational condition of the apparatus.
