If during these cycles the anomaly disappears and the amplifier works
regularly for more than 15 min. the counting system is reset and the
original conditions established.
The protection acts for excessive SWR, over-temperature and overdrive.
It indicates the problem with warning lights and disables the pilot
exciter.
NOTE: The intervals described are nominal.
1.5 R.F. AMPLIFIERS
The amplifier comprises an RF broadband module with 50 Ohm input/
output impedance ("N" type connectors).
The output power of the module is approximately 250W across the frequency
range while the drive power is 20W; this output power is limited to 250W
to maintain a good level of reliability.
1.6 DEVICE SPECIFICATIONS
Refer to Table (A) for electrical specifications, and to Table (B)
for dimensional and environmental specifications.
