BPF-C650+

Overview

The BPF-C650+ is a lumped LC bandpass filter designed for surface mount applications. It operates within a frequency range of 560 MHz to 780 MHz, providing a center frequency of 650 MHz and a bandwidth of 220 MHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination type. It is housed in a compact HU1186 package style. The device supports board mounting and functions reliably within an operating temperature range of -40°C to +85°C.

Feature Summary

• Surface mount construction for automated assembly integration
• Lumped LC topology for precise bandpass filtering characteristics
• Standard 50 Ohm impedance matching for RF system compatibility

Applications

• RF signal conditioning in communication infrastructure
• Frequency selection in receiver front-ends
• Signal processing in wireless transmission systems

Procurement Notes

Verify the specific datasheet version and mechanical dimensions against the HU1186 package standard before integration. Confirm that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application. Ensure PCB layout accommodates the surface mount footprint correctly to maintain signal integrity and thermal performance.

Selection Notes

Select this component when a fixed 650 MHz center frequency with a 220 MHz bandwidth is required. The lumped LC design offers a compact solution compared to distributed filters. Ensure the application environment stays within the specified -40°C to +85°C operating range. Verify that the 50 Ohm system impedance aligns with the surrounding circuitry to minimize reflection losses.
