This high linear preamplifier was developed in 1…2 GHz directional radio link. It is suitable especially for applications where a high intermodulation distortion ratio and at the same time a high input sensitivity are used. As example for RADAR preamplifiers or for digital directional radio distance with DVBT-DVBS-COFDM and QPSK modulation. The coupling happend through 3dB hybrids, which guarantee an excellent input SWR and linearity of the preamplifier. A high stimulus capability and simultaneously a low noise figure makes the preamplifier for many applications usable. The voltage supply via coax cable (remote power supply) or direct at the case is possible.
  • Low noise figure
  • High IP3
  • Good input return loss (S11)
  • Static protection (ESD) at preamplifier input
  • Overvoltage protection and reverse polarity protection
  • Remote power supply via output connector
  • Solder pin for direct power supply
  • Analog and digital transmission systems
  • Measurement and laboratory equipment
  • Amplifier does not contain a coaxial relay!
  • Maximum input power 10 mW
