'FP' Series Bandpass Filters
FP40137'FP' Series Bandpass Filters
Sinclair's FP series cavity filters are the building blocks of the finest antenna systems. These filters pass a band of frequencies while attenuating frequencies on either side of the desired frequency band.
The insertion loss of the passband may be preset at the factory or adjusted in the field.FP40103
The amount of attenuation (selectivity) can be increased by increasing the insertion loss or using multiple cavities in series. At 800 MHz and above, filter design must recognize the extremely close tolerances required to assure flawless performance over temperature when small variations in electrical wavelength mean significant changes in frequency response curves.
Consequently, Sinclair engineers have carefully adapted the FP series filters for a variety of applications in the 806-960 MHz frequency range.

  • Protect one receiver further from front-end overload by carriers of co-located transmitters.
  • Suppress IM generation in one transmitter by protecting it further from incoming carriers of co-located transmitters (usually in conjunction with a ferrite isolator).
  • Suppress sideband noise of a single transmitter on co-located receiver frequencies.
  • Generally, "Protect One from Many."
