  • Page 13: General Description

    The PJ2000M comprises two PJ1000M MosFet amplifiers connected with an HC2- 2 hybrid combiner. The PJ2000M is housed in a 19” rack-mountable frame, 20U high, of which 5U are free and may be used for an exciter or other equipment.

  • Page 14: Electrical Description

    The HC2-2 Hybrid Combiner has the function of a driver power divider coming from the exciter and of a combiner of the amplifiers power output, to generate the antenna final output. The diagram of the connections beetween the components of the PJ2000M is shown in Figure 2. Figure 2 [1] HC2-2 OUT 1 PJ1000M “B”...

  • Page 17: Installation Procedure

    6.3 Installation After all the connections have been made between the individual devices, it is necessary to perform the following operations to install the PJ2000M: With the help of Figure 2, verify that all the connections are in perfect condition.
  • Page 18 PJ2000M Increase the exciter output power in order to have 2000W power on the PJ2000M. Switch the meter selector of the HC2-2 to the RFL position and verify that the meter needle is at zero. Note: To verify the correct balancing of the two PJ1000M modules, do switch the meter selector of the HC2-2 to UNBAL position and verify that the power isn't more than 20W.

  • Page 19: Maintenance

    FIRST LEVEL MAINTENANCE 7.3 Ordinary Maintenance The only regular maintenance needed by PJ2000M, is the periodic substitution of the blowers, and the cleaning of dust filters and any dust accumulated inside the amplifier. The time between overhauling of the blowers depends upon several environmental factors, temperature, humidity, dust pollution etc.
