RFFM4201

3.3V TO 5V, 2.4GHz TO 2.5GHz HIGH POWER

FRONT END MODULE

RFFM4201 is a 1 x 1 MIMO module that is intently specified to address IEEE

802.11b/g/n WiFi 2.4GHz to 2.5GHz customer premises equipment (CPE) applica-

tions. The module has an integrated three-stage linear power amplifier, Tx harmonic

filtering and SPDT switch. The RFFM4201 has fully matched input and output for a

50

 system and incorporates matching networks optimized for linear output power

and efficiency. The RFFM4201 is housed in a 6mm x 6mm laminate.
