Super Filter
The Super Filter is designed for Base Transceiver Station (BTS) to solve the pervasive problems of interference caused by the intrusion of unwanted signals from competing network operator's adjacent frequencies.
Such interference can cause dropped calls and cross talk, and it prevents network operators from utilizing all of their available radio spectrum. All these will lead to lost revenue and unsatisfied customers.
Our Super Filter adopts customizable IF SAW (surface acoustic wave) filter that can perfectly filter out the undesired signal. And a lower-noise amplifier is added inside to compensate the attenuation due to filtering before the signal is transmitted to the BTS.
It has a compact size and can be installed on the top of telecommunication tower and below the BTS antenna.
