MA04713

Overview

The MA04713 is a Surface Acoustic Wave (SAW) filter manufactured by Golledge Electronics Ltd. It operates at a center frequency of 902.5 MHz with a bandwidth of 25 MHz. The device features an insertion loss of 3.5 dB and is housed in a compact 6-SMD, no-lead package. Designed for RF applications, it supports wireless communication systems requiring precise signal filtering within the specified frequency range.

Feature Summary

• Surface Acoustic Wave technology for efficient RF signal processing
• Optimized for cellular band applications around 900 MHz
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Cellular mobile phone RF front-end modules
• Wireless communication base stations
• RF transceiver signal conditioning circuits

Procurement Notes

Verify the specific datasheet revision and pinout configuration against your schematic before integration. Confirm that the 902.5 MHz center frequency aligns with your target regulatory band requirements. Ensure proper grounding and matching network design to achieve the specified 3.5 dB insertion loss performance in your final assembly.

Selection Notes

Select this component when a SAW filter is required for the 900 MHz cellular band with a 25 MHz bandwidth. Consider the 6-SMD package size for board space constraints. Evaluate the 3.5 dB insertion loss against system link budget requirements. Compare alternative frequencies if operating outside the 902.5 MHz nominal specification.
