PRO-LPZ 1450

Coaxial Low-Pass Filter for passing the frequency range 1100 - 1450 MHz
Description
  • The PRO-LPZ 1450 is a high-performance Low-Pass filter with low insertion loss and high rejection.
  • The product is developed using stepped impedance design principles (Zolotarev characteristic), providing rejection up to 8 GHz.
  • Adding the PRO-LPZ 1450 to e.g. a radio system in the L-Band ensures that no RFI (Radio Frequency Interference) in form of harmonics or other spurious emissions in the stop band from the radio system itself will be broadcasted by the antenna.
  • The PRO-LPZ 1450 attenuates radiation from outside sources, such as adjacent radio systems transmitting in the stop band of 1450 MHz – 8 GHz. If stopband up to e.g. 12 GHz is requested, please ask for availabilty.
  • The Low-Pass filter is typically used with base station transmitters, but its mechanically rugged design makes it perfectly suited for mobile and marine applications as well.
