Abstract

The invention discloses a negative group delay Gysel power divider and a design method thereof. The Gysel power divider with a negative group delay characteristic comprises five sections of branch lines, two negative group delay units, two isolating resistors, a matching resistor, a signal inputting port and two signal outputting ports. Therefore, by the power divider, design can be finished by preliminary definition of required insertion loss and group delay value. The negative group delay Gysel power divider has the characteristics that the insertion loss is low, and an input port is matchedwith an output port well. The negative group delay Gysel power divider can be applied to the group delay characteristic in a compensating microwave system.

Description

technical field [0001] The invention relates to a microwave power divider, in particular to a Gysel power divider with negative group delay characteristics and a design method thereof. Background technique [0002] The power splitter is referred to as a power splitter for short. It has the function of separating and combining signals. It is widely used in antenna feed networks and power amplifiers. In the past few decades, the research on power splitters has focused on the characteristics of power splitters such as unequal power distribution, frequency band widening, miniaturization, dual-frequency response, and harmonic suppression, but lacks the characteristics of power splitter group delay. Research. [0003] Compared with the Wilkinson power divider, the Gysel power divider introduces two ground isolation resistors, which overcomes the problem that the Wilkinson power divider has poor heat dissipation under high power conditions because the isolation resistance between ...
