What is Ceramic Filter

Center Frequency (Symbol: f0; Unit: Hz)

It signifies the frequency in the center of the pass band width. However, the center frequency for

some product is expressed at the point where the loss is minimum.

●

Pass Band Width (Symbol: PBW; Unit: Hz)

Signifies a difference between the two frequencies where the attenuation becomes 3dB from the

level of the minimum loss point.

●

Insertion Loss (Symbol: IL; Unit: dB)

Expressed in the input and output level ratio at the point of minimum loss in dB. The insertion loss

for some product is expressed in the input and output level ratio at the center frequency.

●

Ripple (Unit: dB)

If there are peaks and valleys in a pass band width, the ripple expressed the level difference of

voltage between the maximum peak and minimum valley and it is expressed in dB.

●

Attenuation Band Width (Symbol: ABW; Unit: Hz)

Signifies a difference between the two frequencies where the attenuation becomes the specified

values (dB) from the level of minimum loss.

(Example: Expressed at a point where the attenuation becomes 20 dB in case of 10.7 MHz filter.)

●

Selectivity (Unit: dB)

Expressed as the attenuation of the detuning point from the center frequency.

(Example: The attenuation that ±9 kHz was detuned from the center frequency in case of 455 kHz

filter.)

●

Spurious Response (Symbol: sp; Unit: dB)

Expressed as the difference of voltage ratio between minimum attenuation point in the stop band

range and minimum loss point in the pass band width by using dB (The stopped range is specified

with each filter).

●

Spurious

Signifies the frequency response based on the parasitic (unwanted) vibration against the frequency

except the fundamental vibration.
