Filter design and debugging (LC cavity microstrip waveguide bandpass, low-pass, high pass) duplexer design 10 years of experience in HFSS simulation design and engineering, with a design frequency of terahertz. All designs are based on practice and guided by theory. Remote after-sales service is available, and long-term cooperation can provide on-site service!
Hello, this filter is only made for reception, it is not usable as an output filter for a transmitter. So the power it can accept is very low, of the order of a few mW. 73 Denis F6CRP
What is the insertion loss (i.e loss in the passband) of this filter? Judging from the spectrum analyzer images on page 11 of the manual, it seems to be 4dBm but that shurely can not be the case?
The reference level on my spectrum anlyzer is 0 dB. You can note that insertion loss is very closed to 4 dB on low bands, reach more or less 5 db on higher bands.
Encore un travail intéressant, bien présenté... qui donne envie de se lancer dans l'aventure 73 ph
Merci Philippe, petit montage tout simple et sans surprise pour un futur récepteur. 73 Denis

Hi sir what is the max power in watts it can handel de VU3ZNL

@@radiorider8249 Thank you for your response Denis.
Starting 7 mhz and upward the filters of these stages are overcoupled! You should decrease the capacitance between the LC cells
Yes i fully agree, this will be the next step. Thanks for your comment.
