1500W FM Low Pass Filter

1500W FM Low Pass Filter 1500W FM Low Pass Filter – Low-pass filter with directional coupler provides a direct and reflected DC voltage. The test gantries feature a wideband equalized network. The equalizer maintains a constant RF level for the diodes across the FM band, which results in the same voltage at all frequencies. Each filter is carefully tested with our HP8753ES network analyzer. 86-110MHz 1,200 watts maximum.
Order 9 Chebyshev typology.
Ultra low loss Teflon PCB; tightly controlled dielectric constant.
#8 large AWG inductors.
0.12 dB maximum insertion loss; 0.1dB typical.
-28dB return loss;-33dB typical.
-47dB rejection at 176MHz. This is the first harmonic of 88MHz
Directional Coupler Specifications Direction: minimum 20 dB
2.5V voltage in front of 1000W
