EFCH1575TCA1

Overview

The EFCH1575TCA1 is a Surface Acoustic Wave (SAW) filter manufactured by Panasonic Electronic Components, designed for GPS RF applications. It operates at a center frequency of 1575.42 MHz with an impedance range of 50-100 ohms for unbalance-to-balance conversion. The component utilizes a compact 2.0x1.4 mm package with a 5-pin layout and exhibits an insertion loss of approximately 1.1 dB.

Feature Summary

• Surface Acoustic Wave technology for high-frequency signal filtering
• Integrated unbalance-to-balance impedance transformation
• Compact surface-mount footprint optimized for space-constrained designs

Applications

• GPS front-end signal chains
• RF receiver input stages
• Navigation system modules

Procurement Notes

Verify the manufacturer part number against official Panasonic documentation to ensure authenticity. Confirm that the specific suffix matches the required pin configuration and packaging style. Cross-reference technical specifications with the latest datasheet to validate performance parameters for your specific design requirements before procurement.

Selection Notes

Select this component when designing GPS receivers requiring precise 1575 MHz filtering with minimal insertion loss. Ensure the circuit board layout accommodates the 2.0x1.4 mm package dimensions. Verify that the 50-100 ohm impedance range aligns with the surrounding RF circuitry for optimal signal integrity and balance conversion.

Part Context

This SAW filter belongs to Panasonic's portfolio of RF components tailored for navigation systems. It addresses the need for high selectivity in L1 band GPS signals while maintaining a small physical profile suitable for modern mobile and automotive electronics.

Replacement Considerations

Consult official Panasonic substitution guides for verified alternatives. Do not assume functional equivalence with generic SAW filters due to specific impedance and frequency response requirements.
