SEQUOIA COMMUNICATIONS

Sequoia Communications is a fabless RF semiconductor company setting new benchmarks in multimode design and integration. The FullSpectra™ common architecture, developed by Sequoia Communications, allows a single-chip transceiver to support multiple air interface protocols enabling effective communications across numerous wireless air standards.

Based on the FullSpectra architecture, the SEQ7400 is a single-chip, 7-band multimode transceiver, that supports GSM/GPRS/EDGE/WCDMA/HSPA and TD-SCDMA. The SEQ7400 uses a single polar modulator transmit architecture for all air standards, delivering the highest levels of integration in the industry. Typically external WCDMA LNAs and SAW filters are required, but the SEQ7400 integrates these functions into the chip and is the industry’s first true monolithic receiver providing significant savings in bill-of-material (BOM), size and cost. The line of multimode RF products created by Sequoia Communications will continue to address the three key handset metrics of cost, size and power consumption.

Sequoia Communications' engineering and management team is comprised of seasoned veterans from the mobile semiconductor industry with extensive experience from world-class companies such as QUALCOMM, Nokia, Maxim, Skyworks, Texas Instruments and Mitsubishi.
