RFMD introduces FEM for 900 MHz ISM band applications

Radio-frequency microelectronic component maker RF Micro Devices Inc (RFMD) of Greensboro, NC, USA has announced the availability of its RF3858 front end module (FEM), which supports multiple Tx/Rx applications in the 900 MHz ISM band, including Smart Energy/Advanced Metering Infrastructure (AMI).

RFMD says that the highly integrated, single-chip RF3858 addresses the increasing requirements for aggressive size reductions in the 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, with 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, and a Tx harmonic filter, says the firm. Furthermore, the FEM reduces the number of external components by approximately 80% versus discrete designs. The RF3858 is packaged in a 8.0 mm x 8.0 mm x 1.2 mm over-molded laminate package with backside ground, and is priced at $2.28 in quantities of 10,000 (available immediately).
