Key facts
High-power signals transmitted by base stations might saturate the test equipment. The CCI bandpass filters eliminate this effect by blocking unwanted signals outside of the frequency range of interest and enabling a clear visualization of the signals present in the uplink range.
The bandpass filters consist of multiple cavity resonators to provide optimal performance for the passband with low insertion loss, low intermodulation and high power handling. The small form factor and low weight make the filters ideal for measurements in the field.
Uplink signals are more susceptible to interference. During measurements performed close to a base station, high power downlink signals may interfere in the uplink frequency range.
A bandpass filter keeps the influence of downlink signals away, allowing you to analyze the uplink frequency range and spot the presence of interferers more easily and quickly.

The bandpass filter eliminates the influence of BTS signals and enables the easy identification of an interferer in the network.
The BPFC bandpass filter from CCI provides optimal performance for the passband with low insertion loss and low intermodulation. Excellent return loss delivers the best match to the antennas and base station.
The bandpass filter consists of multiple cavity resonators to achieve 20 dB of rejection within the specified frequencies. Extensive temperature compensation is employed to insure frequency stability over the specified temperature range.
