    i ran across this part i had pulled from somthing acording to the data sheet for hitachi witch i beleve it is it is a power amplifier. this is a link to the data sheet for it it is part #pf0030
    http://www.qsl.net/n9zia/cell2900/pf0030.pdf
    i do not understand much of the diagram and i have no idea what apower amplifer does. if anyone could please tellme what this divice does and explain what these mean it would help. i don't know what apc voltage is, or all of this stuff.
    Electrical Characteristics ​
    (Ta = 25°C)​

    Item Symbol Min Typ Max Unit Test Condition​
    Drain cutoff current I​
    DS — — 500 mA VDD = 17 V, VAPC = 0 V
    Total efficiency
    hT 35 40 — % Pin = 2 mW,
    2nd harmonic distortion 2nd H.D. — –50 –30 dB V
    DD = 12.5 V,
    3rd harmonic distortion 3rd H.D. — –50 –30 dB Pout = 6 W (at APC controlled)
    Input VSWR VSWR (in) — 1.5 3 — Zin = Zout = 50
    W

    Output VSWR VSWR (out) — 1.5 — —
    Stability — No parasitic oscillation — Pin = 2 mW, V​
    DD = 12.5 V,
    Pout = 6 W (at APC controlled),
    Zin = 50
    W,
    Output VSWR = 20:1 All phases,

    t = 20 sec

    any ideas what i could do with such a divice?
    thanks
