SE4120S-R

RF Receivers Overview

The SE4120S-R is a SiGe RF receiver designed for GPS applications, operating at the standard L1 frequency of 1575.42MHz. It features a 46-WLCSP package with dimensions of 2.20x2.18mm. The device supports a supply voltage range of 2.7V to 3.6V and draws a typical receive current of 10.5mA. It operates within a temperature range of -40°C to 85°C.

RF Receivers Feature Summary

• Integrated SiGe technology for compact GPS signal reception
• Surface-mount WLCSP packaging for space-constrained designs
• Optimized for low power consumption in mobile applications

RF Receivers Applications

• GPS navigation systems
• Mobile communication devices
• Personal navigation devices (PNDs)

RF Receivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as discontinuation may affect long-term availability. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

RF Receivers Selection Notes

Select this component when a small form factor is required for GPS integration. The WLCSP package offers significant size reduction compared to traditional QFN options. Evaluate power constraints against the 10.5mA typical current draw to ensure battery life targets are met in portable designs.

RF Receivers Part Context

This part belongs to Skyworks' SiGe RF receiver family, specifically tailored for global positioning system signals. It complements other models like the SE4110L and SE4150L by providing a different package solution suitable for high-density PCB layouts while maintaining standard L1 band performance characteristics.

RF Receivers Replacement Considerations

Check for SE4120L or SE4120L-R if pin compatibility allows, though package differences exist. Verify functional equivalence with newer generation receivers from Skyworks or competitors if this specific model is unavailable due to discontinuation.
