Ujjdwiurgh For Ham Radio Amplifier Analyzer HF Radio Compatible 433MHz Low Pass Filter 400-470MHz 7th-Order Elliptic Function LPF

A low-pass filter passes signals below the cutoff frequency while attenuating signals above it. It's often used to suppress high-order harmonics in electromagnetic signals or to filter out high-frequency noise after a mixer, acting as a frequency . This filter can significantly attenuate signals above 470 MHz, with a harmonic suppression capability of approximately 50 dBc. This is a 7th-order elliptic function low-pass filter with superior filtering steepness compared to other filters.
