PLATH SIR 511X

PLATH SIR 5110 & 5115 HF RX

The HF receiver SIR 511X, with an instantaneous analogue bandwidth of 29.5 MHz, covers the frequency range from 0.5 to 30 MHz. Its modular and flexible design allows various configurations to incorporate different mission scenarios from manual interception to automatic communication intelligence (COMINT) and sets the benchmark for new generation of compact HF search and interception receivers.
The receiver provides a coherent digital bandwidth of 12.288 or 29.5 MHz which can be used in one block or in freely distributed sub-channels over the entire frequency range.
The SIR 511X competes effectively with dedicated narrowband receivers and has some of the best technical features of any digital wideband receiver.

  • Exceptional SFDR ≥ 105 dB
  • SIR 5110, 16 x 768 kHz bandwidth (12.288 MHz overall)
  • SIR 5115, 40 x 768 kHz bandwidth (29.5 MHz overall)
  • Min. detectable signal -139 dBm @ 125 Hz
  • SIR 5110 up to 120 virtual narrowband receivers
  • SIR 5115, up to 600 virtual narrowband receivers
  • No internal spurious responses
  • go2signals support
