Highpass Filters

Highpass

Highpass Filters are used in applications that require a range of high frequencies to be passed while attenuating lower out of band frequencies.

TTE’s highpass filters are available for any -3dB frequency from 100 Hz to 4 GHz. For frequencies above or below that range please contact TTE for assistance.

If you can't find what you are looking for please contact us today!
We will be glad to help you with your filter needs.

HIGHPASS FILTER FORMULAS:

TIME DELAY:

This example uses the delay data for an HB11-12MHz-50.
To calculate the delay at 62.5% of the cut-off frequency we find the normalized delay is 4Div below the reference of 2.5S. Each division is 0.5mS. Thus, the normalized delay is 2.5S minus 2S. Which is 500mS at 19.2 MHz. The cut-off frequency is 12 MHz.

Delay = (Time in seconds) / Fc – Cut off Frequency)
           = (500)/(12*106)
           = 41.67nS

NOTES:

TTE offers its passive filters in the smallest practical sizes available; PCB, SMT or connectorized (BNC or SMA) cases are typically utilized, depending on the specific filter design.
