FIELD-EFFECT TRANSISTOR

A transistor consisting of a source, a gate, and a drain. Current flow is controlled by the transverse electric field under the gate [7].

FILAMENT

The cathode of a thermionic tube, usually a wire or ribbon, which is heated by current passing through it [6].

FILM ICs

Conductive or nonconductive material deposited on a glass or ceramic substrate. Used for passive circuit components, resistors, and capacitors [14].

FILTER

A 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 AMPLIFIER

The final stage of amplification in a transmitter [12].

FIRST DETECTOR

See MIXER [18].

FIXED BIAS

A constant value of bias voltage [6] [7] [13].

FIXED RESISTOR

A resistor having a definite resistance value that cannot be adjusted [1].

FIXED SPARK GAP

A device used to discharge the pulse-forming network. A trigger pulse ionizes the air between two contacts to initiate the discharge [12].

FLAT LINE

A transmission line that has no standing waves. This line requires no special timing devices to transfer maximum power [10].
