FIELD-EFFECT TRANSISTORA transistor consisting of a source, a gate, and a drain. Current flow is controlled by the transverse electric field under the gate [7]. | ||
FILAMENTThe cathode of a thermionic tube, usually a wire or ribbon, which is heated by current passing through it [6]. | ||
FILM ICsConductive or nonconductive material deposited on a glass or ceramic substrate. Used for passive circuit components, resistors, and capacitors [14]. | ||
FILTERA selective network of resistors, capacitors, and inductors that offers comparatively little opposition to certain frequencies, while blocking or attenuating other frequencies [6] [9]. | ||
FINAL POWER AMPLIFIERThe final stage of amplification in a transmitter [12]. | ||
FIRST DETECTORSee MIXER [18]. | ||
FIXED BIASA constant value of bias voltage [6] [7] [13]. | ||
FIXED RESISTORA resistor having a definite resistance value that cannot be adjusted [1]. | ||
FIXED SPARK GAPA device used to discharge the pulse-forming network. A trigger pulse ionizes the air between two contacts to initiate the discharge [12]. | ||
FLAT LINEA transmission line that has no standing waves. This line requires no special timing devices to transfer maximum power [10]. | ||
