    LOW PASS FILTER

    DETI’s low pass filters are ranging from a few MHz up to 18 GHz and can handle power up to 1000 W (10 kW peak). In order to cover such a large range of frequencies and power, DETI designs filters using lumped or distributed elements. Lumped elements filter allows low frequencies decive to keep a small size, but a limited to around 1 GHz. PCB filters use distributed elements printed on a microwave substrate to make inductors and capacitors.

    Low pass filters (LPFs), also called high cut filters, attenuate frequencies higher than the cut-off frequency. LPFs differ from High pass filters (HPFs) in their assembly because in a low-pass filter, the resistor comes before the capacitor, whereas HPFs are mounted in the reverse order. High-pass filters can improve the reception of a signal by eliminating aliasing effects that degrade the quality of the transmission of the signal. By coupling them with high pass filters, they can be used to design bandpass filters.

    The main attributes of a low pass filter are:

    • Fmax: It is the upper bound of the filter’s pass band. Indeed LPFs usualy let the signal pass from DC up to Fmax with a max VSWR and insertion losses.

    • Rejection frequency: It is the low bound from with a specified rejection is defined.
