Caelera offers the RF3858 front end module (FEM) introduced by RF Micro Devices, Inc., a global leader in the design and manufacture of high-performance radio frequency components and compound semiconductor technologies.
The RF3858 front end modules support multiple Tx/Rx applications in the 900 MHz ISM band, including Smart Energy/ Advanced Metering Infrastructure (AMI).
The highly integrated, single-chip RF3858 front end module addresses the increasing requirements for aggressive size reductions in RF front end designs for portable equipment.
The RF3858 combines a 1-watt 915 MHz power amplifier capable of 31.5 dBm of output power and consisting of a double-pole double-throw (DPDT) Tx/Rx transfer switch with low insertion loss and high isolation, a low noise amplifier (LNA) with bypass mode as well as a Tx harmonic filter.
The RF3858 reduces the number of external components by approximately 80% versus discrete designs, greatly minimising product footprint, accelerating design-in time and reducing overall assembly costs.
The RF3858 front end module is packaged in a small 8.0mm x 8.0mm x 1.2mm over-moulded laminate package with backside ground, minimising next level board space and allowing for simplified integration.
