F
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]. |
