SKY65723-81

RF Amplifiers Overview

The SKY65723-81 is a low-noise amplifier front-end module integrating a GPS/GNSS/BDS pre-filter. It operates within the 1.559 GHz to 1.606 GHz frequency range, providing a gain of 16.8 dB and a noise figure of 1.5 dB. The device functions on a supply voltage of 1.62 V to 3.6 V with a current consumption of 4.2 mA. Key linearity metrics include an OIP3 of -8 dBm and a P1dB of -14.5 dBm. It is housed in a compact 6-MCM (1.7x2.3 mm) surface-mount package suitable for mobile applications.

RF Amplifiers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or official Mouser/DigiKey channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to PCB assembly. Ensure ESD protection protocols are followed during handling due to the exposed pad package design.

RF Amplifiers Selection Notes

Select this module when integrated filtering and amplification are required for L-band satellite signals. Compare against the SKY65723-11 if specific notch filtering for cellular bands like B13 is needed instead of broad pre-filtering. Evaluate thermal performance and supply voltage compatibility with target host processors.

RF Amplifiers Part Context

Part of the SKY65723 series from Skyworks Solutions, focusing on RF front-end integration for location services. The series targets miniaturization needs in smartphones and IoT devices by combining passive filter components with active amplification stages into a single small-footprint package.
