MA05255

Overview

The MA05255 is a Surface Acoustic Wave (SAW) filter manufactured by Golledge Electronics Ltd, designed for Global Positioning System (GPS) applications. It operates at a nominal center frequency of 1575.42 MHz. The component utilizes a surface-mount device (SMD) package with four pins and exhibits an insertion loss of 2.2 dB while maintaining a 50 Ohm impedance characteristic. It functions within an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Engineered specifically for GPS signal processing
• Provides precise RF filtering at the L1 band frequency
• Supports compact circuit designs via SMD packaging

Applications

• GPS receiver front-end modules
• GNSS navigation systems
• Satellite positioning devices

Procurement Notes

Verify the specific datasheet version to confirm exact mechanical dimensions and pin configurations prior to integration. Ensure that the supply chain documentation explicitly identifies the component as a SAW filter for GPS applications to avoid substitution errors with general-purpose RF filters.

Selection Notes

Select this component when designing circuits requiring dedicated filtering for the standard GPS L1 frequency. Consider the 2.2 dB insertion loss and 50 Ohm impedance requirements during schematic design. Confirm that the operating environment remains within the specified -40 °C to +85 °C thermal limits for reliable performance.
