R&K RF Filters

(BP Series / LP Series / HP Series)

R&K’s BP series products are semi-custom lumped-constant bandpass filter, composed of a variable capacitor and inductor.

The model numbers and their specifications listed in the table are some examples of previously manufactured products. Both center frequency and passband width can be customized based on the customer’s requirement as long as they are within our technical capability.

As our standard specification, the center frequency of 10MHz to 1500MHz and passband width of 5 to 20% of the center frequency can be covered. Passband width will be 10% if there is no request.

Our standard specification has 4-stage filter configuration, but it can be changed to 5-stage as an option for the customer who needs shaper cut-off characteristic.

R&K’s LP & HP series products are semi-custom lumped-constant low & high pass filter products, composed of a variable capacitor and inductor.

The model numbers and their specifications listed in the table are some examples of previously manufactured products. Both cut-off frequency and circuit characteristics can be customized based on the customer’s requirement as long as they are within our technical capability.

As our standard specification, the cut-off frequency of 1MHz to 1000MHz can be covered. If no specification for the circuit characteristic, we make a Chebyshev filter with sharp cut-off. The Butterworth filter with less sharp cut-off and the Bessel filter with the least sharp cut-off can be also made according to the customer’s request.

Our standard specification has 3-stage filter configuration, but it can be changed to 4-stage as an option for the customer who needs sharper cut-off.
