AM1575B1561

Overview

The AM1575B1561 is a ceramic band-pass filter manufactured by Anatech Electronics Inc., designed for surface-mount applications. It operates at a center frequency of 1.57542 GHz with an 18 MHz bandwidth and features a 50 Ohm impedance. The component utilizes a 16-SMD module package, measuring 1.039 inches in length and 0.630 inches in width (26.40mm x 16.00mm). It exhibits an insertion loss of 4.5 dB and complies with RoHS standards.

Feature Summary

• Utilizes ceramic technology for stable band-pass filtering performance
• Designed for surface-mount installation via a 16-SMD module configuration
• Optimized for precise center frequency operation at 1.57542 GHz

Applications

• GPS receiver front-end filtering
• Satellite navigation signal processing
• GNSS system integration

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and mechanical drawings before finalizing design integration. Ensure that the 16-SMD footprint matches the target PCB layout dimensions precisely. Confirm RoHS compliance status if required by environmental regulations for the intended market. Cross-reference the manufacturer's part number to avoid confusion with similar series components.

Selection Notes

Select this component when a fixed center frequency of 1.57542 GHz is required for L-band applications. The 18 MHz bandwidth suits narrowband signal extraction needs typical in global positioning systems. Consider the 16-SMD package size for available board space constraints. Evaluate the 4.5 dB insertion loss against system sensitivity requirements to ensure adequate signal integrity after filtering.

Part Context

This component belongs to the category of passive ceramic filters produced by Anatech Electronics Inc. These devices are engineered for high-reliability RF applications where compact size and stable performance are critical. The AM1575B1561 specifically targets the GPS L1 band, providing essential out-of-band rejection for navigation receivers.

Replacement Considerations

Consult official substitution lists from Anatech Electronics Inc. for direct equivalents. Verify that any alternative maintains the 1.57542 GHz center frequency and 16-SMD package compatibility. Ensure impedance and bandwidth specifications match to prevent circuit mismatch.
