POWER AMPLIFIERS

Table 6-3 shows the RF Power outputs for the transmitter modules in each frequency band.

Table 6-3: 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 6-8, that will ﬁ t into a standard subrack.

19” rack mountable. All transmitters and power ampliﬁ ers are rated for 100% continuous duty.
