CB5717

DESCRIPTION

CB5717 is a highly integrated RF Front-End Integrated Circuit which incorporates key RF functionality needed for IEEE 

802.11a/n/ac WLAN systems operating in the 5.15-5.9GHz range. CB5717 integrates a high-efficiency high-linearity power 

amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, LO rejection, and harmonic filters all 

in one device. 

CB5717 has simple and low-voltage control logic, and requires minimal external components. A power detector is also 

integrated for accurate monitoring of output power from the PA. 

CB5717 is assembled in a compact, low-profile 2.5x2.5x0.55mm 16-lead QFN package. CB5717 is the ideal RF front-end 

solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11ac.
