of the output power level and the switch ON selector (9 Fig.1A e 8 Fig.1B).
1.4 AUTOMATIC FREQUENCY CONTROL
The operating frequency is governed by a thermally-compensated, reference
oscillator working within a phase-locked loop (PLL).
The TEX20-N.V. reaches frequency lock within a maximum of 30 seconds.
1.5 CONTROL CIRCUITS
The control circuits allow automatic control of output power, maintaining
the chosen power level across the entire operating band. Furthermore another
circuit protects the final stage against excessive VSWR or short circuits.
1.6 RF AMPLIFIER
The RF amplifier is a wide-band design and guarantees an adjustable power
output of 2 to 20 watts across the entire band.
A low-pass filter enables the TEX20-N.V. to be used as a low power transmitter,
connected directly to an antenna.
