RFMW Ltd. announces design and sales support for a family of high-performance front-end modules (FEMs) designed for improved range in low-power WAN (LPWAN), IoT applications.
The Skyworks Solutions SKY66420, SKY66423 and SKY66421 support designs in the 860 to 930 MHz frequency range. The SKY66420, SKY66423 are fully featured FEMs that include a power amplifier, low-noise amplifier and T/R switch. The SKY66421 is a power amplifier. All 3 devices are pin-to-pin compatible and provide transmit power up to 27 dBm while drawing 280 mA from a 2.0 to 4.8 V supply. Receive gain for the full-featured FEMs is 18 dB with noise figure of 1.5 dB. Increased output power and improved receive gain effectively quadruple communication range compared to standalone, system-on-chip (SoC) solutions.
Supporting LoRA, SigFox and other LPWAN technologies, these devices will reduce total system Icc by as much as 30% and are suitable for operation from coin cell batteries supporting applications such as smart metering, home automation and asset tracking.
Offered in a compact, 3 x 3 mm MCM package.
