Custom Wide Band High Pass Filters
RLC Electronics’ Customized Wide Band High Pass Filters are designed for operation over the frequency range of 20MHz to 18 GHz. Good VSWR in the pass band, low insertion loss, and good rejection are achieved by utilization of both distributed and lumped component techniques. Miniaturized construction makes the units suitable for many uses.

Pass Band VSWR: F-90’s 1.5 to 25 x fc(4 GHz max) F-100’s 1.8 to 5 x fc (12.4GHz max) 2.0 to 8 x fc (18.0GHz max) |
Power Rating: 2 watts avg. Impedance: 50 Ohms Environmental: MIL-E-5400, Class 1A Connectors: Type SMA Female |
* Refers to number of filter sections N; total number of reactive elements is given by 2N+1.
** From cut off frequency to frequency where VSWR ceases to be specified
To designate the filter desired use:
1: “90” or “100” for model number 2: Cut off frequency in MHz |
3: Number of sections |
Example:F-90-100-4-R is an F-90 series, 100 – 2500 MHz pass band, 4 section filter, SMA (female) connectors.
