WITH ADVANCED METERING INFRASTRUCTURE (AMI) and other applications in the Industrial, Scientific, and Medical (ISM) band gaining in popularity, the RF3858 front-end module is a promising solution for portable equipment in need of size reduction. It also reduces the number of components outside of the core chipset. The RF3858 contains a power amplifier (PA) transmit/receive (Tx/Rx) transfer switch, low-noise amplifier (LNA) with bypass mode, and matching components. That LNA operates on DC supply current of 32 mA and +5 dBm input power. The 1-W, 915-MHz PA can deliver +31.5 dBm output power. Aside from the LNA, the PA is combined with a double-pole double-throw (DPDT) Tx/Rx transfer switch and a Tx harmonic filter. The module offers 27 dB gain with a noise figure of 1.3 dB. P&A: available now; $2.28 in 10,000Q.
