RFX8050W数据手册RF/IF射频/中频RFID的射频前端（LNA+PA）规格书PDF

描述 Description

Please note: RFX8050W is being discontinued and is not recommended for new designs.

RFX8050W is a highly integrated, single-chip, single-die RFeIC (RF Front-endIntegrated Circuit) which incorporates key RF functionality needed for IEEE802.11a/n/ac WLAN system operating in the 5.15-5.85GHz range. The RFX8050Warchitecture integrates a high-efficiency high-linearity power amplifier (PA), low noiseamplifier (LNA) with bypass, the associated matching network, LO rejection, andharmonic filters all in a CMOS single-chip device.

RFX8050W has simple and low-voltage CMOS control logic, and requires minimalexternal components. A directional coupler based power detect circuit is alsointegrated for accurate monitoring of output power from the PA.

RFX8050W is assembled in an ultra-compact, ultra-thin 2.5x2.5x0.4mm 16-leadQFN package. With support to direct battery operation, the RFX8050W is ideal RFfront-end solution for implementing 5GHz WLAN in smartphones and many othermobile platforms.
