132MHz-142MHz bandpass filter with a center frequency of 137MHz

A bandpass filter is a filter that allows frequency components within a specific frequency range to pass through, but attenuates frequency components in other ranges to extremely low levels, as opposed to a bandstop filter. An example of an analog bandpass filter is a resistor-inductor-capacitor (RLC) circuit. These filters can also be generated by combining low-pass and high-pass filters.
★ Simulation of the filter using simulation software:
Simulation results are:
loss = 0.2dB, center = 134.8MHz, bandwidth = 10MHz,
meeting expectations.
★ Rendering:
★ Physical image:
★ Production process:
1. Design board prototyping
2. Master-level hand-mounting
3. Manual reflow soldering
4. SMA connector soldering 5. Board cleaning solution
, clean and smell good (completed)
When making the board, remember to check the box for adding custom code at the specified location, board thickness 1.6mm, the rest are default, color is arbitrary.
