    The PA Power Supply, and its output voltage range, varies with the transmitter model. For VX150 to VX600 transmitters, the output voltage range is between +18 and 53 V dc. For VX1 to VX2 transmitters, the output voltage range is between +23 and 65 V dc.

    The PA Power Supply, and its output voltage range, varies with the transmitter model. For VX150 to VX600 transmitters, the output voltage range is between +18 and 53 V dc. For VX1 to VX2 transmitters, the output voltage range is between +23 and 65 V dc. The output voltage is regulated based on a serial control input from the Power Supply Interface PWB (A4).
  • Page 11 VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL DESCRIPTION Exciter PWB The Exciter PWB (A1) accepts external audio program information and generates the modulated RF drive source for the IPA PWB (A6). It performs all primary control functions of the transmitter.

  • Page 12: Rf Stage

    PA PWB(s) The PA PWB(s) accepts the RF + Bias drive from the System Interface PWB (for VX150 to VX1) or from the Splitter PWB (for VX1.5 and VX2), and PA volts input from the Power Supply Interface PWB. The RF output of the PA PWB(s) is controlled by a combination of gate bias set point, RF drive and PA volts.
  • Page 13 VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL DESCRIPTION Combiner PWB Used in VX1.5 and VX2 transmitters only. The Combiner PWB combines the RF output signals from both PA PWBs and applies it to the Directional Coupler (A11). Directional Coupler The Directional Coupler (A11) samples the transmitter's forward and reflected power and generates the Fwd Pwr Sample (A11J2) and Refld Pwr Sample (A11J3) signals applied to the Exciter PWB and System Interface PWBs for protection and monitoring.
