Low Pass Filter 800 Watt
Lebih Lengkap Mengenai Low Pass Filter 800 Watt
This is our economical high power low pass filter. This model is intended for use with our 300W, 350W, 600W and 700W pallet amplifiers.
0.25 dB insertion loss maximum; 0.20 dB typical.
-22dB return loss maximum; -25dB typical.
Metal clad silver teflon caps from Semco.
#8 Awg Inductors.
-60dB rejection at 176MHz. That's the 1st harmonic of 88MHz
Size: 3 inches wide x 7 inches long.
Each unit is sweep tested on an HP 8753D network analyzer to meet our specifications.
.25dB maximum insertion loss, better than -20dB return loss from 88-108MHz. Maximum insertion loss occurs at 108MHz.
RF connectors are not included.
Mounts to customers chassis with 8-32 screws. 3/8 inch PCB standoffs or washers are required between the bottom of the PCB and chassis to prevent shorting of the inductors. 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 intended for use in 50 ohm systems only.
What does a low pass filter do? A low pass filter passes all frequencies below its cutoff frequency and attenuates all frequencies above it. This filter is designed to attenuate harmonics produced by RF amplifiers. For example, if an RF amplifier is operating at 100MHz it will produce a carrier at 200MHz, 300MHz etc. These carriers can interfere with other radio services and they can attract regulatory agencies to your door step. Low pass filters will not eliminate in band spurs.
