QPQ1298 is a high-performance BAW (Bulk Acoustic Wave) filter. Its function description is as follows:
1. Frequency Filtering: It has a 160MHz bandwidth in Band 41, with a frequency range from 2515MHz to 2675MHz, which can efficiently separate and filter signals in line with the frequency requirements of Band 41.
2. Signal Transmission: It has a low insertion loss of 2.5dB, which ensures that the loss of the signal passing through the filter is minimized, thus improving the overall performance of the system.
3. Signal Interference Suppression: The attenuation is greater than 44dB or even more than 45dB in the near band, which can effectively suppress unnecessary signal interference. It can also effectively suppress Wi-Fi signals and other interference signals, meeting the demanding Wi-Fi coexistence requirements.
4. Power Handling: The power handling capacity is up to +29dBm. It can operate stably in high-power applications. For example, in a small base station, it can operate for more than 10 years at 95°C with an incident power of +29dBm of a typical LTE signal.
5. Operating Environment Adaptability: The operating temperature range is from -40°C to +95°C, which can adapt to various harsh environmental conditions.
6. Packaging and Structure: It adopts a 3-pin 2.00mm×1.60mm×0.73mm SMT package, which is small in size and easy to assemble, saving space for circuit boards. It complies with RoHS directives and is lead-free, which is environmentally friendly.
7. Input and Output Mode: It operates in a single input single output mode, which simplifies the signal processing process and is convenient for connection and use in the circuit.
