Abstract

The invention relates to an L-wave-band miniature active microwave variable phase-inverting balancing power divider and filter which comprises the components of a single-pole double-throw switch chip WKD102010040, a low-noise amplifier chip WFD007016-L15, a power divider and a balanced filter. The power divider is composed of a specific compact structure and a three-dimensional integrated structure. The balanced filter comprises input / output ports which are adhered on the surface, and a four-grade parallel resonance unit which is realized by a band-shaped linear structure. The structures of the components are realized according to multilayer low-temperature co-fired ceramic technology. The L-wave-band miniature active microwave variable phase-inverting balancing power divider and filter has advantages of effective realization for variable and reversible phase, easy debugging, small weight, small volume, high reliability, high electric performance, high temperature stability, high batch consistency of the electric performance, low cost, high suitability for batch production, etc. The L-wave-band miniature active microwave variable phase-inverting balancing power divider and filter is suitable for occasions and corresponding systems with high requirements for size, electric performance, temperature stability and reliability in communication in corresponding microwave frequency band, satellite communication, etc.

Description

technical field [0001] The invention relates to a filter, in particular to an L-band miniature active microwave variable phase-inverting balanced power division filter. Background technique [0002] In recent years, with the rapid development of miniaturization of mobile communication, satellite communication and national defense electronic systems, high performance, low cost and miniaturization have become the development direction of the microwave / radio frequency field.
