Low pass filter LPF 1200W 1.8-54 MHz LDMOS BLF188XR MOSFET power amplifier

  
1200W LPF for 160 6 meter amateur radio bands including WARC. 160 and 80 meter filters are Chebyshev 7-order C-input, while other are Chebyshev 5-order L-input. Elsie 2.78 software was used for modeling and optimization.

6 meters, 10/12 meters, 15/17 meters, 20/30 meters, 40 meters, 80 meters, 160 meters. The arrangement is such that with no relay pairs energized, the 160m filter is active.

To activate any other filter segment, the control line for that band is switched to ground. T130 Micrometals cores are used and copper enamel wire diameter 1.2mm or 1.6mm for HF inductance, 2.2mm diameter for 54MHz.

All capacitors are MLCC AVX and Johanson C0G/NPO dielectric. Board size 230 x 130 mm, height 35 mm. FR4 PCB with copper thickness 50 um. The item "Low pass filter LPF 1200W 1.8-54 MHz LDMOS BLF188XR MOSFET power amplifier" is in sale since Tuesday, May 15, 2018.
