250W Low Pass Filter
[ LPF250]
25dB maximum insertion loss, better than -20dB return loss from 88-108MHz. Maximum insertion loss occurs at 108MHz. # RF connectors are not included. A coax can be soldered directly or PC mount N connectors may be used. We do offer an aluminum enclosure for this filter: Visit this page: Aluminum Enclosure # The components used are Semco 500V metal cased micas and # 14 awg machine wound inductors. This design is based on an Elenos exciter output section. # Mounts to customers chassis with 8-32 screws. 1/ 4 inch PCB standoffs or washers are required between the bottom of the PCB and chassis. Installing the filter in a metal chassis is suggested to provide shielding and good thermal conductivity in high power installations. # This low pass filter is best suited for our 15, 45, 80, 150 and 175W pallets. # This low pass filter is intended for use in 50 ohm systems only
