B39881B7925P810

RF Multiplexers Overview

The B39881B7925P810 is a surface-mount RF duplexer designed for cellular communication systems. It operates within the GSM/EDGE frequency bands, specifically handling low-band transmission from 824MHz to 849MHz and high-band reception from 869MHz to 894MHz. The component utilizes a 9-SMD, leadless package configuration suitable for automated assembly processes. Technical specifications indicate minimum attenuation levels of 50.00dB for the low band and 45.00dB for the high band, with maximum attenuation reaching 55.00dB and 50.00dB respectively. This device is part of the B7925 series manufactured by Qualcomm.
