Filters

Filters are extremely important in systems. They reject unwanted harmonics of an LO, the other sideband in an upconverter, limit the band of an RF input or isolate channels in a transceiver. Below is a list of Spacek Labs filter products.

	Wide Bandpass Filters	Wide bandpass filters are created using a combination of Low Pass Filter and a High Pass Filter.
	Narrow Bandpass Filters	These are low loss filters that have sharp skirts.
	Low Pass Filters	Low Pass Filters can reject out to five times the cut-off frequency and have low loss.
	High Pass Filters	These filters use cut-off waveguide to reject frequencies below the desired frequency.
