Freescale Semiconductor has released a new reference design for small office/home office (SOHO) base station applications that is partially powered by two advanced gallium arsenide (GaAs) monolithic microwave integrated circuits (MMICs).
The comprehensive baseband-to-antenna reference design combines the QorIQ Qonverge BSC9131 base station system-on-chip (SoC) with Freescale RF radio boards, and is a multi-protocol solution that scales across a range of cellular bands to ease developers’ transition from 3G to 4G LTE. Sourcing the base station SoC and RF devices from the same vendor can speed time to market and help ensure optimal compatibility and integration.
The devices deployed on the radio boards are the MMZ25332B and MMZ09312B amplifiers. Both provide high linearity and power efficiency and can cover multiple bands, including Band 1/WCDMA and Band 13/LTE. Along with the radio board, the MMICs can be easily tuned to support multiple UMTS frequency bands.
The QorIQ Qonverge BSC9131 device features a scalable architecture that supports a range of air interfaces, including LTE, LTE-FDD and TDD, and WCDMA/CDMA. It combines Power Architecture cores and high-performance StarCore DSPs with Multi-Accelerator Platform Engine (MAPLE-B) technology for baseband processing. It also features interconnect fabric and next-node process technology, as well as glueless RFIC communication and antenna interfaces.
