6 meter Receiving Low Loss Band-pass Filter BPF 50 – 54 MHz

 

Measured data on the assembled filter with HP8753ES full 2-port calibrated are presented
Achieved results on a built 6 meter Band pass filter:

1.8 MHz < -100 dB

3.8 MHz < -100 dB

7.1 MHz < -89 dB

14.15 MHz = -71 dB

21.2 MHz = -58 dB

28.4 MHz = – 47 dB

50 MHz = -0.4 dB 

52 MHz = -0.4 dB

54 MHz = -0.55 dB

70 MHz = -38 dB

70.5 MHz = -39 dB

88 MHz= -66 dB

98 MHz= -68 dB

108 MHz= -64 dB

144 MHz = -55 dB

146 MHz = -54 dB

288 MHz = -38 dB

432.1 MHz = -44 dB

440 MHz = -38 dB

These excellent results were achieved by careful selection of components and design of the filter.
