Front-end module for ISM and metering applications

July 26, 2018 // By Jean-Pierre Joosting
The SKY66119-11 from Skyworks is a high performance transmit/receive front-end module (FEM) that provides range extension for Internet of Things (IoT) applications including smart metering and Industrial, Scientific and Medical (ISM) systems.

The device’s transmit chain features +30 dBm output and the receive chain features a low-noise amplifier (LNA) with a 1.3 dB noise figure. The module delivers 30.5 dBm Pout at 400 to 500 MHz to enable more than 4x the range versus standalone system-on-chip (SoC) systems and covers multiple unlicensed bands. 

The FEM also has a fast switch on/off (<4μs in receive mode and <2μs in transmit mode) that provides rapid timing and multi-protocol arbitration. The module also boasts a high-efficiency power amplifier for longer battery life and comes in a small footprint with MCM (28-pin 6.0- x 6.0-mm) surface mount technology packaging.

The SKY66119-11 FEM has been designed into reference designs with products from Silicon Labs and Texas Instruments.
