Problems solved by technology

Almost all non-reciprocal radio frequency devices in the prior art need to use magnetic materials such as ferrite to break the time-reversal symmetry, and the magnetic material lattice is different from that of CMOS (complementary metal-oxide-semiconductor) integrated circuit processing technology. Compatible, making it difficult for these RF devices to be integrated with system circuits, which is not conducive to the miniaturization of equipment

The nonreciprocal power divider comprises a dielectric substrate and at least one Wilkinson powerdivider, wherein a port of the Wilkinson power divider is used as a radio frequency port of the nonreciprocal power divider; the Wilkinson power divider is arranged on the top surface of the dielectric substrate, each branch of the Wilkinson power divider comprises a filter, and each filter is composed of at least two resonators; the back surface of the dielectric substrate is provided with a plurality of variable capacitance diodes, a plurality of signal feed-in circuits, a plurality of metallized through holes and a plurality of modulation ports; the modulation ports are used for receiving modulation signals, each modulation port is connected to one metallized through hole through the signal feed-in circuit, one end of each variable capacitance diode is connected to one end of a resonator through the metallized through hole, and the other end of each variable capacitance diode is grounded. The non-reciprocal power divider is realized without bias of any magnetic material, and has theadvantages of integration with a circuit and the like.

Description

technical field [0001] The invention relates to semiconductor technology, specifically a non-reciprocal power divider and an electromagnetic wave transmission device. Background technique [0002] In mobile communication systems, RF non-reciprocal devices are essential system components. Non-reciprocity means that electromagnetic waves traveling in two opposite directions in a medium will exhibit different electromagnetic wave transmission characteristics. [0003] Common RF non-reciprocal devices include isolators and circulators. Isolators protect signal sources from high-power reflected signals, and circulators direct electromagnetic waves. Non-reciprocal devices in the prior art usually use magnetic materials and external magnetic field bias to break the time-reversal symmetry so as to realize the non-reciprocity of electromagnetic wave transmission. These non-reciprocal devices often exist due to the use of magnetic materials Disadvantages such as high loss, large vo...
