Abstract

The invention discloses a microwave amplitude equalizer with a lumped structure. The equalizer includes surface-mounted input and output interfaces (1, 2), a series branch surface-mounted capacitor C (7), and a parallel branch surface-mounted inductance L ( 3, 4), absorption resistance (5, 6, 8). The technical solution includes: series capacitance and parallel inductance determine the amplitude-frequency characteristic of the equalizer to be a positive slope characteristic, absorption resistance determines equalization amount and insertion loss, and reactance elements (3, 4, 7) load resistance to realize absorption of microwave power. The invention has the advantages of small size, light weight, low cost, high reliability, etc., good batch consistency of electrical performance, and can be mass-produced, and is suitable for radio frequency front-ends of systems such as radar, broadband communication, and electronic countermeasures.

Description

technical field [0001] The invention belongs to the technical field of microwave circuit design, and more specifically relates to a microwave amplitude equalizer with a lumped structure. Background technique [0002] In practical engineering applications, the amplitude-frequency characteristics of broadband microwave devices fluctuate. According to different performance requirements, the wideband radio frequency system transmitter will not only use multi-stage amplifiers, but also cascade switches, attenuators, power dividers and other devices. Due to the unevenness of the device itself and the influence of cascaded standing waves, the circuit gains of or loss) unevenness will superimpose and affect each other, which will seriously worsen the in-band unevenness of the transmitter and cause the output waveform to deteriorate. [0003] Equalizers can solve the above problems, which are usually constructed using waveguides or coaxial cables. However, they are often bulky, hea...
