Low Pass Filters

Low Pass Filters  - DISCONTINUED

Microlab’s low pass filters are designed to suppress harmonics and out of band noise and interference, to improve signal quality in high power system applications and bench testing. The design used is known as rod and bead and is constructed of alternate lengths of high and low impedance transmission lines tuned to provide the proper frequency response. The design ensures a low loss pass band response down to at least 40% of the cut-off frequency. In the stop band rejection of at least 55 dB occurs at 150% of cut-off and extends typically for several octaves. When compared to lumped element construction, the single piece rod and bead filter has far fewer solder joints, is better supported, and operates cooler with a better VSWR.
