455 kHz ceramic band-pass filter

455 kHz ceramic filter, high selectivity, very good filter for HF receivers for AM and SSB

SPECIFICATIONS:
- Bandwidth (-3dB): 4 kHz
- Selectivity: 70 dB (typical)
- Impedance: 2 kΩ
- Dimensions: 11 x 7 mm, h 8.5 mm

50 Ω matching 3 dB loss

 

T1 + T2 = 6 + 40 coil
wire Ø 0,25mm toroid FT37-43
C1 = 150 pF
C2 = 220 pF silver mica
B 3dB=4 kHz
B 6dB=4.8 kHz
B 60dB=8.8 kHz
B 70dB= 9.7 kHz

This circuits has been used only for the selectivity test to obtain the 50Ω matching
