RF Micro Devices Inc. unveils the highly integrated RF3858 front-end module that addresses the increasing requirements for aggressive size reductions in the RF front end designs for portable equipment. It is tailored to support multiple Tx/Rx applications in the 900MHz ISM band, including Smart Energy/AMI.

The highly integrated, single-chip RF3858 combines a 1W 915MHz power amplifier capable of 31.5dBm of output power, with a DPDT Tx/Rx transfer switch with low insertion loss and high isolation, LNA with bypass mode, and a Tx harmonic filter.

The RF3858 reduces the number of external components by approximately 80 per cent versus discrete designs, greatly minimising product footprint, accelerating design-in time and reducing overall assembly costs. The RF3858 is packaged in a small 8mm x 8mm x 1.2mm over-moulded laminate package with backside ground, minimising next level board space and allowing for simplified integration.

The RF3858 is priced at Rs.105.28 ($2.28) in quantities of 10,000 and is available immediately.
