    Model 60/40S1G18B 3.2.3 A10, A11, A12, A13 Output Power Amplifier The output power amp is assembled on thin film substrates. The GaN devices, 90˚ quad couplers and bias board are the same as the driver amp. The gain should be about 0.5dB less than the driver amp. It delivers approximately 15-20 watts of RF power.

  • Page 43: Power Supply

    Model 60/40S1G18B POWER SUPPLY The Model 60/40S1G18B contains three switching power supplies. The input voltage range to the power supply is 90–264 VAC, 47-440Hz, selected automatically.

  • Page 46: Troubleshooting

    Model 60/40S1G18B TROUBLESHOOTING CAUTION: The microwave transistors used in the Model 60/40S1G18B amplifier are GaN/GaAs FETs. These devices are very reliable when installed in a suitable circuit, but they can be easily damaged by improper troubleshooting or handling techniques. The gate junctions of the GaN/GaAs FETs have a high input impedance and are susceptible to static damage or damage due to the use of an ungrounded soldering iron.

    <0.1V when S1 is depressed. S1 is normally open; it is closed only when it is depressed. The amplifier should change state every time the POWER switch is depressed. 8. If all voltages are correct and the unit still does not operate, contact AR to arrange for repair or replacement of the A14 Control Panel.

  • Page 58: Cooling System

    Model 60/40S1G18B COOLING SYSTEM The liquid cooling system is a closed system which will operate for years without maintenance. The coolant level should extend into the coolant reservoir, with the heat exchanger full for optimum cooling. This will provide protection to 5° C (41˚F) for operation and -10˚C (14˚F) for storage. The coolant manufacturer is Koolance (www.Koolance.com).
  • Page 59 These modules are not field-repairable and should never be opened outside of AR’s Microelectronics Lab. The modules in these product lines have a security label on two sides of the modules between the housing and lid/cover. If the security label is removed and or cut, the warranty of the module will be voided.
