WHY CHOOSE RFM WLS-SERIES?
Small size and low cost
High level of integration supports effi cient
design cycles for faster time-to-market
Best-in-Class Ti SoC provides reliability
and customer assurance
Minimal external circuitry required to complete
a radio design / minimize BOM costs
RFM WLS-Series Modules provide a solution that is design-optimized for high RF perfor-
mance and to be size-efficient. These products are manufactured in an automated, high
volume environment to provide a high-quality, low-cost solution.
The WLS-Series modules represent best-in-class WLAN and Bluetooth coexistence technology
on a single-chip and include high-efficiency RF front-end circuits plus a DC-DC converter.
The module is designed to fit into small spaces, with minimal external circuitry required
to complete a radio design. These attributes result in a solution that is cost-effective and
reduces the product design cycle.
Wi-Fi and Bluetooth Compliant . To ease Wi-Fi and Bluetooth certifications, all three modules
comply with IEEE 802.11b/g/n and WLS1273L complies with 11a/b/g/n, while the WLS1271L
and WLS1273L modules comply with Bluetooth v 4.0 plus EDR, Power Class 1.5 + BLE.
FCC / ETSI Certifiable . Like all RFM Short-Range Radio products, the WLS-Series
Modules are FCC and / or ETSI certifiable.
Standard Order Increments . WLS-Series products are shipped in tape and reel with standard order
increment of 1,000 on 13” reels.
