Description
Bessel Low Pass Filter 7.0 MHz 5 Pole 50 Ohm BNC In/Out RF Lab Bench Test
This is a 7.0 MHz Bessel low pass filter in a compact aluminum enclosure, with BNC connectors on dedicated IN and OUT ports. The filter is rated at 50 Ohm impedance on both input and output. Bessel filters are characterized by a maximally flat group delay (linear phase response), making them particularly useful in applications where pulse shape preservation matters alongside frequency rejection. The 5-pole topology provides a moderate roll-off slope while maintaining the Bessel response characteristics.

Applications
Bessel low pass filters are used in RF, analog signal processing, and test & measurement applications where both frequency selectivity and phase linearity are important. A 7.0 MHz low pass filter is commonly used to suppress harmonics and high-frequency noise in baseband and intermediate frequency (IF) signal chains, in pulse and waveform testing setups, and in signal conditioning before analog-to-digital conversion. The 5-pole Bessel design is well suited to applications such as telecommunications baseband filtering, oscilloscope signal path conditioning, arbitrary waveform generator outputs, and lab bench RF test setups where it is important not to distort pulse rise times or group delay. The 50 Ohm impedance matches standard RF coaxial test infrastructure throughout.
This Bessel Low Pass Filter (7.0 MHz, 5-Pole, 50 Ohm) has been pulled from a working environment and visually inspected. The aluminum enclosure shows light cosmetic wear consistent with normal use, but is structurally intact with no cracks or damage. Both BNC connectors — IN and OUT — appear clean and undamaged. The paper identification label on top is intact and legible. Please view our photo set and contact us if you have any questions.
