PAGING REFERENCE SENSOR BOARD (OPTIONAL)
The Paging Reference Sensor Board is an additional option for the Paging Modulator (CI-PM-3) and
System Alarm Relay Board (SCARB) for simulcast systems that require high stability of paging signals.
The board works in conjunction with the paging modulator’s on-board PLL circuit. It is designed to
protect paging systems from external reference failures and indicate that a failure has occurred. The
alarm output will be triggered if the external reference fails.
POWER AMPLIFIERS
Table 3-3 shows the RF Power outputs for the transmitter modules in each frequency band.
Table 3-3: RF Power Outputs
Band Frequency Transmitter
VHF Highband 136 - 174 MHz 0.5 to 8.0 Watts
UHF 400 MHz 406 - 470 MHz 0.5 to 8.0 Watts
UHF T-Band 470 - 520 MHz 0.5 to 6.0 Watts
UHF 700 / 800 MHz 768 - 869 MHz 0.5 to 3.0 Watts
UHF 900 MHz 896 - 960 MHz 0.5 to 3.0 Watts
If a higher RF power output is required, the transmitter may be used as an exciter to drive a power
amplifi er. Codan Radio Communications manufactures a 30 Watt power amplifi er for VHF highband
and UHF 400 MHz, shown in Figure 3-22 that will fi t into a standard subrack.
