Functions

• Excellent Signal Filtering: It has excellent rejection characteristics, which can effectively suppress signals outside the 790 - 890 MHz frequency band and allow only signals within the passband to pass through with low attenuation. This ensures the purity of the output signal and reduces interference from other frequency - band signals.
• Low Insertion Loss: The filter features low passband insertion loss, which means that the signal attenuation within the passband is very small. This allows the filtered signal to maintain a high - enough strength and quality, without significant distortion or attenuation, ensuring the integrity of the signal during the filtering process.
• Miniature Shielded Package: Housed in a miniature shielded package, the CBP - 840C+ offers good electromagnetic compatibility.
• The shielding design can prevent electromagnetic interference from the outside environment from affecting the filter's performance and also prevent the internal electromagnetic field of the filter from leaking out, reducing interference with other components.

Applications

• Wireless Communication Base Stations: In the 790 - 890 MHz frequency band used by some wireless communication systems, such as GSM and DCS systems, the CBP - 840C+ is used to filter the uplink and downlink signals of the base station2. It can separate the useful signals from the complex electromagnetic environment, improve the signal - to - noise ratio, and enhance the communication quality and anti - interference ability of the base station.
• Radio and Television Broadcasting: In the field of radio and television broadcasting, the CBP - 840C+ can be used in the transmitter and receiver systems of some radio and television stations. It filters the broadcast signals to ensure that the transmitted signals are within the specified frequency band and have high purity, and at the same time, filters out the interference signals in the received signals to improve the reception quality.
• Microwave Communication Systems: In some microwave communication links, when the operating frequency is in the 790 - 890 MHz range, the CBP - 840C+ is used to filter the microwave signals. It helps to improve the signal - to - noise ratio of the communication link, suppress the interference of adjacent frequency - band signals, and ensure the reliable transmission and reception of microwave signals.
• Testing and Measurement Equipment: The CBP - 840C+ is also widely used in testing and measurement equipment such as spectrum analyzers and signal generators. It can be used to filter the input and output signals of the equipment to ensure the accuracy and stability of the test results. For example, in a spectrum analyzer, it can filter out the interference signals outside the measured frequency band to make the measured spectrum more accurate
