power amplifiers and a Power Management Unit (PMU), with one switching regulator.
The ISM4343-WBM-L151-EVB integrates clock, Wi-Fi/BT and front end into the smallest
form factor LGA Module. The ISM4343-WBM-L151-EVB IEEE 802.11 b/g/n enables
wireless connectivity to the simplest existing sensor products with minimal engineering
effort. ISM4343-WBM-L151-EVB reduces development time, lowers manufacturing costs,
saves board space, simplifies certification compliance, and minimizes customer RF
expertise required during development of target applications.
The ISM4343-WBM-L151-EVB provides the highest level of integration for a wireless
system, with integrated single band Wi-Fi and BT/BLE based on Cypress’ IEEE802.11
b/g/n single-stream and BT/BLE 4.1 with support for antenna diversity and provisions for
supporting future specifications. The ISM4343-WBM-L151-EVB also supports BT 4.2LE
Secure Connection via the Cypress stack. Integrated power amplifiers, LNAs and T/R
switches for the 2.4 GHz WLAN band, are also included, greatly reducing the external
part count, PCB footprint, and cost of the solution.
