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.
