Delivering Efficiency to Wireless Communication Systems

Wupatec has unique IPs to significantly decrease the power consumption of wireless communication RF Front End (RFE). With the ever increasing need for broadband data (5G handset, 5G eMBB, Public Safety Network, Wifi 6 …), the power hungry and narrow band Radio Front End amplifier is a major roadblock to finally unleash all of the benefits of true Software Defined Radio (SDR).

Wupatec’s unique architecture of his envelope tracking (ET) modulator, coupled with main stream GaN process delivers an ultra-compact and cost effective solution for 5G MIMO Antenna, with outstanding performances (200 MHz of SBW, Efficiency > 90%). Furthermore, the uniqueness of ET implementation enable broadband amplifiers, needed to support inter-bands carriers aggregation, corner stone of 5G.
