Sonar Amplifier Matching Circuit for Stable Resonance Bandwidth

The patent applies parameter changes by introducing a variable capacitor that can adjust its capacitance value dynamically. This allows the matching circuit to maintain optimal impedance matching across a broader frequency range, thereby expanding the transmission power stability band while keeping the device transformer-free and compact. The variable capacitance parameter enables the system to adapt to different operating frequencies without requiring a large transformer.

The patent implements dynamics by using a variable capacitor that can change its capacitance value in response to different operating conditions. This dynamic adjustment capability allows the matching circuit to maintain resonance matching across a wider frequency range, enabling the system to preserve transmission power stability while operating over an expanded frequency band. The dynamic nature of the capacitor contrasts with fixed-component traditional designs.

The patent applies mechanics substitution by replacing the mechanical transformer with an electronic matching circuit consisting of capacitors and inductors. This substitution eliminates the need for a large magnetic core and windings, significantly reducing device size while maintaining the voltage amplification capability through resonant impedance matching. The electronic circuit achieves the same functional outcome as the transformer but with a compact footprint.
