3G/LTE transceiver from Fujitsu eliminates SAW filter and LNA

Fujitsu has introduced a new 3G/LTE transceiver, MB86L10A which can work without need of interstage SAW filters and low-noise amplifiers (LNAs). This mobile phone RF IC features backward compatibility with a high-level programming model (API) for radio control using DigRF/MIPI D3G and D4G open standard digital interfaces. This device supports 3GPP LTE/WCDMA/EGPRS based mobile phones by featuring quadband GSM/EDGE and up to five WCDMA or LTE bands in a single-phone configuration.

MB86L10A is optimized for compressed mode operation. MB86L10A has eight outputs while simultaneously supporting advanced multimode power amplifiers. The Receiver part (RX) provides nine inputs supporting LTE, WCDMA and GSM/EDGE. The RF front end eliminates the need for LNAs and SAW filters. It also consists of 5 additional ports to enable RX diversity in WCDMA and LTE modes. The receiver also incorporates anti-aliasing filters, digital channel filters, digital gain control and high-dynamic-range ADCs.

The MB86L10A supports GSM (GSM850, EGSM900, DCS1800, PCS1900), WCDMA (Bands I, II, III, IV, V, VI, VIII, IX, X and XI) and LTE (FDD Bands 1, 3, 4, 6, 7, 8, 9, 10, 11, 13, 17 and TDD band 38 or 40). The transceiver includes dual 3G and 4G DigRF interfaces to the baseband IC to support all generations of basebands, SPI and/or GPOs control PAs, switching regulators and antenna switches. A microcontroller is available inside this chip to manage timing and control.

"The Fujitsu MB86L10A LTE multimode transceiver is the first of its kind to eliminate LNAs and 3G/4G TX and RX SAWs, reducing board area, component count and cost," said Vivek Bhan, senior director of RF Engineering and Product Development for Fujitsu Microelectronics America. "This LTE multimode RF transceiver supports most global band configurations and standard interfaces, and its simple RF API programming reduces radio integration time. The result is smaller radios with optimal time to market for handset manufacturers worldwide."

"It's fantastic to receive direct feedback from leading LTE carriers," said Bhan. "The early feedback on an advanced new standard will help develop a stable product faster, speeding time to market."
