CB5712

Description

CB5712 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. 

CB5712 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. 

CB5712 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. 

CB5712 is assembled in a compact, low-profile 

3x3x0.55mm 16-lead QFN package. CB5712 is the 

ideal RF front-end solution for implementing 5GHz 

high-power WLAN systems supporting multiple 

standards including 802.11ac.
