CB5333替代KCT8248

DESCRIPTION

The CB5333 is a highly integrated, 2.4 GHz front-end module (FEM) incorporating a 2.4 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 2.4 GHz low-noise amplifier (LNA) with bypass, and a 2.4 GHz power amplifier (PA) intended for high-power 802.11ax applications and systems.

The LNA and PA disable functions ensure low leakage current in the off mode. An integrated logarithmic power detector is included to provide closed-loop power control. A Digital Pre-Distortion (DPD) coupler is provided to further improve the linearity of the FEM.

The device is provided in a compact, 24-pin 3 x 5 mm Quad Flat No-Lead (QFN) package.
