How To Order Narrowband Bandpass Filter:

Please specify your order by giving the following data:

1. Center frequency in GHz

2. Percentage bandwidth

3. Lower and upper rejection

4. VSWR in passband

5. Input/output option

6. Size and weight limitation

7. Call us if you have any other specifications

Advantages of Spacek Labs waveguide low pass filters include:

1. Rigorously predictable responses emulating Tchebychev, Butterworth, or other polynomial functions.

2. Low insertion loss and VSWR right up to the cut-off frequency, (No "guard band" required between useable pass band and reject band).

3. Shorter length. Space is not wasted transforming to the required reduced waveguide height since the impedance transformation is accomplished in the filter element steps.

4. Broad stop band. The reject band can extend to 4 and even 5 times the cut off frequency.
