Abstract

The invention discloses a ground coupling type hybrid coupler and a millimeter wave ultra-wideband single-pole single-throw switch, relates to millimeter wave switches, and belongs to the technical field of basic electric elements. The hybrid coupler comprises an upper metal layer and a lower metal layer, wherein the upper metal layer is in a micro-strip line form in the horizontal direction, andthe lower metal layer is a ground coupling type defect horizon, so that the electromagnetic field distribution around the micro-strip line is changed under compact size, the effective inductance of the coupler is strengthened and effective capacitance is imported, thereby realizing a series resonance condition. The single-pole single-throw switch comprises the ground coupling type hybrid coupler,a first control transistor, a second control transistor, a first biasing resistor and a second biasing resistor. The hybrid coupler is capable of effectively compensating the stray capacitance of thecontrol transistors so as to realize low insertion loss, high isolation degree and high power processing ability in an ultra-wideband working frequency range, is simple and compact in structure and small in circuit area, and has excellent scientific application value in the design of millimeter wave integrated circuits.

Description

technical field [0001] The invention discloses a ground coupling hybrid coupler and a millimeter-wave ultra-wideband single-pole single-throw switch, relates to a millimeter-wave switch and belongs to the technical field of basic electrical components. Background technique [0002] Millimeter wave is between microwave and terahertz wave, its long-wave band overlaps with microwave, and its short-wave band overlaps with terahertz wave. It has some excellent characteristics of both microwave and terahertz waves. Single-pole single-throw switches are widely used in wireless communication systems as a key circuit module in millimeter-wave front-end circuits. For example, SPST switches are often used in amplitude keyed communication systems to achieve amplitude modulation, and can also be used to build SPDT-transmit / receive switches in time-division multiplexed front-ends to enable the transmitter and receiver to share the same antenna , providing a more compact solution for full...
