    need ferrite fr circulators

    thanks, but those kind of ferrite are not narrow width ferrite ( that use in circulators).

    need ferrite fr circulators

    hello all I would like to build a circulator. after reading the book "Microwave circulator design" and a CST simulation I need to make a prototype. i am looking for "narrow width ferrite" factories. i found only 5 optional suppliers : "ferrite domen", "Magneton", "CETC" , "TEMEX", "National...

    to find stability of RF amplifier

    where is your transistor is not stable ? if it "in band" you must put resistor (try first at the output network) if it out of band , at higher freq put plr, and if it is at lower freq put prc

    tgf2023-10 help needed x- band PA

    Hi BigBoss. the impedance of unit cell is knowen for the reference at the intrinsic part, ( without the pad), I cant "EM" it b/c i dont know the layers of the cell. i tried to to to add to the normailized model at page 6 an open stub to can to the results at page 7, and it wasnt good.

    tgf2023-10 help needed x- band PA

    thanks bigBoss, i looked at the web and I didn't see at the article any information about the effect of the output pad . I shall be grateful if you show me where this worten. Elad

    tgf2023-10 help needed x- band PA

    Hello. i need to make an 10GHz Pa using the tfg2023-10. i dont have a nonlinear model. just the "R" and "C" at the output, and thay Are different Vs. freq (why ?). I dont have the effect of the output pad ? so i looking for more datasheet about this transistor

    [SOLVED] transistor for lna at 11Ghz

    hello i need to design "THE LNA" at 11GHz. The noise fugure should be less then 0.65 dB at room Temp. i look at 3 atransistors "mgf4941al" "atf360772a" and "nec 32484a" . are there more transistor that i can "play with" ? I look at lna that are on my roof for sat. it writen there n.f. =0.2 dB ...

    poor vswr at phase array antenna at low angle ?

    Why there is poor vswr at phase array antenna when i look at low angle . I heard that there is different between Tx and Rx ? thanks eladg
