The invention discloses a coupling control-based LTCC filtering switch. The coupling control-based LTCC filtering switch comprises two half-wavelength resonators, two feeder lines, a PIN tube, a biasing circuit of the PIN tube and the like, wherein the PIN tube and the biasing circuit thereof are connected to the tail end of one feeder line to control on-off states of a device; when the device is in the on-state, the PIN tube is closed, a signal does not pass through the PIN tube, and extra loss is not generated; when the device is in the off-state, the coupling between the resonators and the feeder lines is controlled to be close to zero through the PIN tube, so that high isolation is realized; compared with the conventional cascading way of a filter and a switch, the filtering switch provided by the invention has lower loss and better isolation effect; and in addition, the LTCC filtering switch is designed by adopting an LTCC multilayered structure, the freedom degree in design is improved while the volume of the device is reduced.
