Around 500 MHz is a bit of an in-between range where lumped element (RC) or waveguide / resonant trough etc type tuning is appropriate. A good start is to look at Amateur Radio amplifiers that work around that frequency and see what sort of output …

10-MHz Butterworth Filter Using the Operational Amplifier THS4001
A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. A low-pass filter is the complement of a high-pass filter. In optics, high-pass and low-pass may have different meanings, depending on whether referrin… Webb17 aug. 2024 · The 30MHz low-pass filter, as QUCS delivered it.
