La description

For suppressing mutual interference that may occur with co-sited transmit and receive antennas.
Key Facts
  • This filter with a power rating of 1000 W is used together with the 500 W and 1000 W transceiver systems for suppressing mutual interference that may occur with cosited transmit and receive antennas. It is mainly used for ship borne applications in order to meet collocation requirements if space for antennas is limited. When connected between the transceiver and the ATU, the filter effectively suppresses spurious emissions due to its high selectivity of 30 dB (20 dB for f > 15 MHz) at f ± 10 %. Tuning is digital by means of RF relays.
  • Main features
    • Covers the entire frequency range from 1.5 MHz to 30 MHz
    • 1000 W CW and PEP at 100 % duty cycle
    • Reduces transmitter noise
    • Reduces harmonics
