【Introduction】

The KCT4525L is a SOI single chip SPDT switch + LNA front end module (FEM) with integrated on-chip bypass switch function.

KCT4525L normally operates at 3.3 V supply with 10mA current consumption at receive mode. The control logic function is also designed to be easily operated by two control voltages among TX / RX / Bypass RF modes.

KCT4525L is assembled in a Ultra small, low-profile 1.5x1.5mm 8-pin DFN package. KCT4525L is the ideal low noise receiving RF front-end solution for implementing 5GHz WLAN systems supporting multiple standards including 802.11a/n/ac/ax/be.
