Front Options
LINK 11 Module
R&S® VX411
  • For operation with wideband AF signals in LINK 11 mode for special data transmissions in defense applications(NATO)
  • For use in conjunction with IF/AF Unit R&S® VZ400D2 and Cipher/LINK 11 Interface R&S® GI412U

  • Design: 1/16 19" front module

    • Note: For standalone RX equipment R&S® VX411 is not required for LINK 11 operation (R&S® VZ400D2 and R&S® GI412U are sufficient)
UHF Circulator Set
R&S® GD430U
  • For interference-free transmission under critical collocation conditions, i.e. many transmitting antennas cosited
  • For reduction of the TX intermodulation by increasing the backward intermodulation attenuation
  • Suppression or reduction of unwanted mixture products which are generated in the transmitter in an electromagnetic environment and which interfere with the actual frequency band
  • Integration: the circulator module of this set can be
    - interfaced in front of the harmonics filter where it is most effective and
    - mounted directly onto the heat sink of the UHF or VHF/UHF power amplifier
