LTE Block (A, B, or C) Bandpass Filter (Lower 700 MHz Band)

Model # 17890

Application:

Paired block LTE operations (A, B, or C) conflict with each other causing interference to one of the blocks.

Solution:

Install a bandpass filter on the affected block that will isolate it from the interfering block.

Features:

  • True "bandpass" response provides isolation from virtually all other out-of-band sources of interference.
  • Models also available for unpaired D and E-block applications.
