1.1. Description
The 6020HRJ/8030J is a single amplifier designed to replace the original 6020HR/8030
amplifier. Many features were added to the design without sacrificing compatibility with
current applications.
The suffix “J” was added to the model number to indicate the JAN quality level of
components used in the power stage. The JAN (Joint ARMY/NAVY) quality level is
imposed on qualified semiconductor manufacturers by the U.S. military. Military
handbook 217-C (Reliability Prediction of Electronic Equipment) defines JAN
components to have a base failure rate five times less than commercial hermetic devices,
and ten times less than plastic devices. Experience has shown that most power amplifier
failures occur in the power stage. Since the 6020HRJ is operated under reduced stress and
fatigue conditions, higher reliability can be expected.
The following protection circuits were added to the amplifier.
1. Short circuit protection (output terminal to output terminal or output
terminal to ground).
2. Bus overvoltage
3. Bus undervoltage
4. Low level control undervoltage
All but #1 are reset automatically when the condition(s) return to normal.
The rectifier and filter are integral to the 6020HRJ/8030J, like the original 6020HR.
