RFC - Radio Frequency Choke

A Radio Frequency Choke (R.F.C.) is a basic inductor used to choke radio frequencies.This kind of inductor will allow DC current to pass through but block AC current in the radio frequency range.In other words,it chokes the radio frequency signal.The value of a chokeRF choke core material - AmfoneDec 22,2012 RF Plate Choke#0183;The best deal on the planet for an amp plate choke is the big Ameritron which is still only $20 which is also sold by RF Parts at $5 more.It will handleRF choke core material - AmfoneDec 22,2012 RF Plate Choke#0183;The best deal on the planet for an amp plate choke is the big Ameritron which is still only $20 which is also sold by RF Parts at $5 more.It will handle

RF plate choke impedance must be high enough to limit RF choke current to safe values.A conservative RF current estimate would be E/Z=I where E is DC plate voltage and Z is choke impedance.A 200 uH choke on 1.8 MHz only has about 2600 ohms reactance,so a 3000 volt anode swing causes 1.15 amperes peak RF current.RF Plate Choke W8JI WebsiteRF plate choke impedance must be high enough to limit RF choke current to safe values.A conservative RF current estimate would be E/Z=I where E is DC plate voltage and Z is choke impedance.A 200 uH choke on 1.8 MHz only has about 2600 ohms reactance,so a 3000 volt anode swing causes 1.15 amperes peak RF current.RFRF Coils - 1 mH to 100 mH - Surplus Sales of Nebraska4-pi plate choke.7 mH.DCR = 50 ohms.0.5D x 0.875L.0.005 wire diameter.NSN 5950-00-648-0929.

Oct 09,2017 RF Plate Choke#0183;The RF choke creates an electromagnetic field on the chokes surface,and within the donut hole.This field attracts the stray RF and chokes it off before it travels down the coax,and it is dissipated within the EM field.Hence the term Choke.In some ways,it almost acts like a ground radial and reflects slightly the RF radiated from the RF Choke Coil (Made Easy) HAM Radio siteOct 09,2017 RF Plate Choke#0183;The RF Choke Coil Solution.Here is the very simple way to make an RF choke coil that will remove your RF feedback troubles.You will be using the same piece of coax that is used for the feedline.In other words,do not make a choke coil,then splice it in later with PL-259s and couplers.This will lower the effectiveness of the choke.RF Choke Coil (Made Easy) HAM Radio siteOct 09,2017 RF Plate Choke#0183;The RF Choke Coil Solution.Here is the very simple way to make an RF choke coil that will remove your RF feedback troubles.You will be using the same piece of coax that is used for the feedline.In other words,do not make a choke coil,then splice it in later with PL-259s and couplers.This will lower the effectiveness of the choke.

I visited the the RF meltdown issue once as a Novice building a 500 watt amp (pair of 813s) and thought PVC tube should work just fine as a plate choke form.Har-har.You don't forget those lessons I also learned about filament chokes in a GG amp when my Dad stormed into my room/shack mad as a jap because I was lighting up all the light bulbs Lattice-wound RF choke replacement,50 years later Aug 18,2005 RF Plate Choke#0183;AES lists some pi-wound 1mH and 2.5mH RF chokes (ferrite core) that look more like the original.Better idea for these?
