4.1 Composition
The PJ20KPS-C/PJ25KPS-C transmitter is made up of modules inserted in a 19” rack. The main
apparatuses are:
• 20 RF amplifier modules at 1.2 kW nominal (PJ20KPS-C)
• 20 RF amplifier modules at 1.4 kW nominal (High efficiency) (PJ25KPS-C)
• 1 Control unit called Master control unit (MCU)
• 1 Hybrid coupler -3dB
• 1 Dummy load
• 4 Power supply
• 1 Service rack (optional)
In standard configuration is supplied with two racks of 40 units as an option you can have a rack
for 40 units of services that can be installed on the right (as shown) or to the left of the transmit-
ter.
4. General Description
The PJ20KPS-C/PJ25KPS-C is a RF amplifier for frequency modulation sound broadcasting. It
is a fully solid-state apparatus of modern design that uses MOSFET as active components in the
FM amplifying modules.This chapter briefly describes the machine’s main features.
