AM1542-1643SD358

Overview

The AM1542-1643SD358 is a Surface Acoustic Wave (SAW) diplexer manufactured by Anatech Electronics Inc. It operates within the frequency range of 1.525 GHz to 1.559 GHz for transmission and 1.6265 GHz to 1.6605 GHz for reception. The device utilizes a 10-SMD module package. Key electrical specifications include a center frequency of 1542 MHz for the transmit path and 1643.5 MHz for the receive path, with a passband width of ±17.0 MHz for both channels. The maximum insertion loss is specified at 4.5 dB.

Feature Summary

• Integrates transmit and receive filtering functions in a single surface acoustic wave component
• Provides isolation between closely spaced frequency bands for duplexing applications
• Designed for compact integration using a 10-SMD module form factor

Applications

• Wireless communication systems requiring RF duplexing
• Base station transceivers operating in L-band frequencies
• Mobile communication infrastructure components

Procurement Notes

Verify the specific datasheet version and qualification status before procurement, as general product listings may not reflect current manufacturing revisions or specific lot traceability requirements. Ensure that the 10-SMD package dimensions align with the target PCB footprint design. Confirm that the 4.5 dB maximum insertion loss specification meets the system link budget constraints for both the transmit and receive paths.

Selection Notes

Select this component when a SAW-based solution is required for separating transmit and receive signals in the 1.5 GHz range. The choice depends on the need for a compact 10-SMD module with defined ±17.0 MHz bandwidths. Consider the 4.5 dB insertion loss limit against system sensitivity requirements. This part is suitable for applications where size constraints are critical and moderate insertion loss is acceptable.
