This filter set is targeted to the contest club stations competing in multi transmitter categories, to SO2R contesters and DX-peditions. Unlike the BPF filters, the BPF Luxury are assembled according to the altered schematic at application of high-quality ferrites made by Micrometalls Co., what improves performance of the filters, particularly isolation between adjacent amateur bands.
Each set includes 6 filters: BPF-1.8 BPF-3.5 BPF-7 BPF-14 BPF-21 BPF-28 (for the 1.8; 3.5; 7; 14; 21; 28 MHz bands accordingly).
The filters are installed between the transceiver and power amplifier, to cut off the interference from the radio emission on another band.
Parameters
Passband loss < 0.6 dB
Characteristic impedace: 50 Ohm

Examples of the filter set responses is available.
Each filter is provided with the frequency response plot measured on the professional automated test bench.
These plots show the actual response in maximum detail for each specific filter included in the set.
