The bandwidth is equal to the 3 dB frequency.
The term bandwidth refers to the width of a filters passband and in the case of a low-pass filter the bandwidth is equal to the 3 dB frequency as shown in the diagram below. Where K is the gain low-pass DC gain or band-pass mid-band gain K is 1 for passive filters Q is the Q factor. An ideal filter has full transmission in the pass band complete attenuation in the stop band and an abrupt transition between the two bands but this filter has infinite order ie the response cannot be expressed as a linear differential equation with a finite sum and infinite latency ie its compact support in the Fourier transform.
