Key Facts The digitally controlled R&S®VK4190 power amplifiers are available in a standard version or a special version with built-in receiver input protection. This option reliably protects the receiver input from destruction in the presence of HF interference on the antenna (caused by nearby transmitters) up to 100 V (RMS) (corresponding to a power of 200 W into 50 ?). The R&S®VK4190 with built-in receiver input protection should be selected whenever undisturbed reception of useful signals is required under extreme conditions.
  • 1000 W transceiver systems
  • Rugged design, high MTBF
  • Special version with built-in receiver input protection available
  • Selective level control option prevents power control from being affected during normal operation by in- service transmitters located nearby
