B220LA0S-T

Overview

The B220LA0S-T is a surface mount bandpass filter manufactured by Knowles Dielectric Labs, designed for signal conditioning applications at 22.0 GHz. It features a 50 Ohm impedance and SMD/SMT termination type. The component operates within a temperature range of -55°C to +125°C. Insertion loss is specified at 3.25 dB. The device is packaged in reels with a factory pack quantity of 100 units.

Feature Summary

• Surface mount bandpass filter design for high-frequency signal conditioning
• Operates at 22.0 GHz center frequency with 50 Ohm impedance
• Wide operating temperature range from -55°C to +125°C

Applications

• Wireless communication systems requiring 22 GHz filtering
• Signal conditioning in RF front-end modules
• Test and measurement equipment operating at microwave frequencies

Procurement Notes

Verify availability status as supply may be restricted or limited depending on region. Confirm packaging format matches reel requirements for automated assembly. Ensure compatibility with 50 Ohm system impedance. Check RoHS3 compliance if required by environmental standards. Validate insertion loss specifications against application tolerances before integration.

Selection Notes

Select this component when a 22.0 GHz bandpass filter is required for surface mount assembly. Consider the 3.25 dB insertion loss impact on signal integrity. Ensure the PCB layout supports SMD/SMT mounting techniques. Verify that the operating environment stays within the -55°C to +125°C range. Compare with other Knowles filters if different frequency points are needed.

Part Context

This part belongs to the Knowles Dielectric Labs Bandpass series, specifically engineered for microwave applications. It is distinct from low-pass variants like L220XH5S-T and other bandpass models such as B274MB1S-T which operate at different frequencies. The product line focuses on high-performance signal conditioning components for RF systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative 22.0 GHz bandpass filters from the same manufacturer only if cross-referencing official datasheets confirms identical electrical and mechanical specifications.
