SEQUANS Communications is launching its newest chip, the SQN1140 RFIC (radio-frequency-integrated circuit) for Mobile WiMAX Wave 2 end-user devices. The chip is a high-performance, low-power RF chip designed to integrate directly with Sequans’ SQN1130 Mobile WiMAX baseband chip for a total Mobile WiMAX 802.16e-2005 solution.

The SQN1140 is a dual-channel MIMO WiMAX RF chip based on CMOS process technology. It delivers dual transmit and dual receive MIMO operation and is designed to support the advanced MIMO technology, mimoMAX, of Sequans’ award-winning SQN1130 baseband chip. Patent-pending mimoMAX enables the SQN1130 to deliver maximum likelihood MIMO performance with low power consumption. The combined Sequans SQN1140 RF plus SQN1130 baseband is the industry’s highest-performing, lowest-power-consuming Mobile WiMAX solution available today.

The SQN1140 consumes only 290 mW of power in receive mode, and 195 mW in transmit mode (single transmit). Other unique features of the SQN1140 include integrated low noise amplifiers (LNAs) and support for several standby modes of operation to further minimize power consumption.

The SQN1140 is available today to selected Sequans customers and will be generally available in Q1 2008. It is already being integrated, with the SQN1130, into multiple end-user devices and SIP modules being developed by Sequans’ ODM partners. Sequans itself is developing a SIP combining the SQN1130 and SQN1140 and an ExpressCard reference design.

The SQN1140 is the fourth Mobile WiMAX chip Sequans has delivered, following a Mobile WiMAX Wave 1 chip in 2006 and two baseband Mobile WiMAX Wave 2 chips in 2007 for base station and mobile stations. All chips are in volume production.
