UniFi® CSR6026™

UniFi® CSR6026™

For Cameras, Gaming, Handsets, Infotainment and Telematics

Description

As more smart and feature-phones started to include Wi-Fi CSR released CSR6026 to provide manufacturers with the lowest cost route to integrating high-performance Wi-Fi without compromising on performance or space. By achieving lower cost points for Wi-Fi integration CSR has allowed Wi-Fi to be integrated into mainstream handsets and portable devices where previously the cost was prohibitive. CSR6026 supports IEEE 802.11b/g and n.

CSR6026 is part of the UniFi range of Wi-Fi devices, the world’s smallest, lowest-cost range of 802.11n-compatible devices. CSR also has a variant on CSR6026, CSR6027, which is WAPI-qualified for the Chinese market.

Product details

Radio

On-chip baluns for single-ended RF input and output
No external trimming required in production
Low output spurii and strong receive blocking performance against cellular bands allows for good coexistence with cellular radios
Front-end control logic can be programmed to support common IEEE 802.11 only and IEEE 802.11 + Bluetooth RF front-end configurations

Transmitter

Support for power compensation of external PA to produce stable transmit power across temperature
Digital predistortion can be used to compensate for non-linearities in external PA
Control of transmit gain settings on a per-packet basis allows transmit power to be optimised for each modulation scheme

Receiver

Fast AGC and wide dynamic range allow for excellent robustness against fading

Frequency Synthesiser

Fully integrated fractional-N synthesiser
