LX5551 and LX5552 from Microsemi Corporation are front-end modules (FEMs) for IEEE 802.11b/g/n applications in the 2.4 to 2.5 GHz frequency range. Addressing small form factor requirements driven by portable devices featuring WiFi connectivity, both modules are offered in a low-profile 3 x 3 mm 16-pin MLPQ package. Each also features an integrated power amplifier, 50 ohm input and output matching, and single-pole-double-throw (SPDT) switch. The LX5551 cuts board space by more than 30% as compared to a discrete design. Additionally, the LX5552 integrates a low noise amplifier (LNA) for improved system performance while saving nearly 50% of the board area required for alternative discrete implementations. Both devices ease RF design complexity by integrating multiple active components and external tuning passives, resulting in significant PCB area savings and minimized solution cost.
