  • Page 51: Theory Of Operation

    3. THEORY OF OPERATION INTRODUCTION The Model 40S6G18A-L RF amplifier consists of a 6.0–18 GHz RF amplifier assembly. The RF amplifier assembly consists of a Pre-Amplifier (Pre-Amp), a Driver Amplifier (Driver Amp), and a 40-watt output module. The power supply section consists of an AC input filter with a circuit breaker switch, a switching power supply, and a regulator circuit.

  • Page 52: Power Supply

    Model 40S6G18A-L POWER SUPPLY There are two power supplies in the 40S6G18A-L amplifier. Power supply PS1 is a switching supply that automatically sets the AC input circuits to the correct connections for the line voltage 90-132 and 180-250 VAC input ranges 50/60 Hz. The outputs of +24, +12 and -12 volts are used primarily in the A1A1 preamp module, control panel A12A1 and interface board A14.

  • Page 55: Maintenance

    4. MAINTENANCE GENERAL MAINTENANCE INFORMATION The Model 40S6G18A-L requires very little maintenance since it is a relatively simple instrument. It is built with thin film substrate etched circuit wiring and solid-state devices that will ensure long, trouble free life. However, should trouble occur special care must be taken in servicing to avoid damage to the devices or the thin film circuitry.
