RSD-1747.500-1842.500-1814-TR-NS1

RF Multiplexers Overview

The RSD-1747.500-1842.500-1814-TR-NS1 is an RF duplexer manufactured by Raltron Electronics, designed for dual-band wireless communication applications. It operates with a receive band of 1.71 GHz to 1.785 GHz and a transmit band of 1.805 GHz to 1.88 GHz. The component utilizes Surface Acoustic Wave (SAW) technology to provide efficient signal separation between the receiver and transmitter paths. It is housed in an 8-SMD, No Lead package, suitable for surface-mount assembly processes. This device integrates filtering functions to support LTE Band 3 and DCS1800 frequency allocations, ensuring minimal interference between adjacent bands while maintaining signal integrity in compact mobile device form factors.
