160 meter High Power Band-Pass filter 4 kW

Top Band - 160 meter 1.8 MHz - 2 MHz band pass filters for BIG GUNS. Band-Pass filters are calculated for more power then presented.

This Topband band-pass filter is specificaly projected for 1.8 MHz to 2 MHz frequency range that can withstand 4 kW linear amplifier. This Magic Band bandpass filter is projected for all international 160 meter frequencies ITU Region 1 1.810MHz-1850MHz, ITU Region 2 1800MHz-2000MHz and ITU Region 3 1800MHz-2000MHz.

In-band insertion loss less than 0.12 dB (1.8 MHz - 2 MHz). Second harmonic is suppressed by more then 40 dB! Images from the network analyzer are shown in the next section. All measurements on assembled filter were done with HP8753ES full 2-port calibrated. 

This graph represents insertion loss - S21 from 1 MHz to 4 MHz.

Short history of 160 meter communication.

The 160 meter band is the oldest radio amateur band and was the staple of reliable communication in the earliest days of amateur radio, when almost all communications were over relatively short distances. The band was allocated on a worldwide basis by the International Radiotelegraph Conference. Since time of inception 160 meter frequency had many obstacles and threats from commercial and military spectrum users, the efforts of a small number of determined 160 meter operators enabled the band to survive. In the UK it was the primary band for mobile operation for many years. The band experienced a rebirth with the demise of LORAN-A in the United States in December, 1980 and the removal of power restrictions below 1900 kHz soon thereafter. Power restrictions above 1900 kHz were removed in March 1984. 160 meters was then no longer regarded as the "orphan" band as it had been for more than half a century.

These filters have band pass filter design that has low insertion loss and low SWR across an entire working band to which it is designed with emphasis placed on maximum possible rejection of second harmonic energy. Our filters are carefully projected to fit approved frequency range. Improving filters and making them better was always our passion. If we notice an aspect where they can be improved we go for it. Fine engineering can be noticed and our products usually exceed our competitors in more then a few things. Each HF bandpass filter is handmade and configured to match the desired characteristics. Also, before packing the filters are checked again to ensure maximum quality.
