Base Transceiver Station Filter & Duplexer

In today’s high-speed mobile networks, base transceiver stations (BTS) use filters with steep skirts that reduce interference by aggressively rejecting out-of-band signals. Sophisticated BTS components such as combiners, duplexers and filter banks can reduce signal levels by more than 110 dB in the rejection band. For those that operate in the LTE band, frequency coverage must reach 3.8 GHz, and during final test it is also necessary to measure the second harmonic above the carrier.

The next-generation Keysight E5080A ENA Series Network Analyzer provides greater precision in filter adjustments, faster throughput and lower costs, and improved operator efficiency.
