Freescale Semiconductor has announced a new reference design that combines the company’s QorIQ Qonverge BSC9131 base station system-on-chip (SoC) with the company’s dual-band RF radio boards. The product completes the link between the baseband and the antenna, with 20mW average power at the antenna. It also integrates RF devices from Maxim and ADI. The reference design can be tuned to over all of the major UMTS bands in the world, from 450MHz to 2.8GHz.
Specifically, the dual-band RF board (BSC9131XRFBD, pictured) includes: 2x2 MIMO, dual F receivers for 2x2 LTE, dual RF transmitters for 2x2 LTE, modulation schemes up to 64QAM, support for bandwidths from 1.4 to 20MHz with maximum Tx output power of +13dBm.
The QorIQ Qonverge BSC9131 supports LTE (Rel. 9), WCDMA (Rel. 99/7/8). LTE performance is 20MHz single sector 100Mbps downlink and 50Mbps uplink. HSPA+ performance is 42Mbps downlink and 11Mbps uplink. It is enabled with 2x2 MIMO and features 2G/3G sniffing and GPS support.
The refrence design is powered by Freescale’s GaAs MMIC devices on the radio board, including the MMZ25332B and MMZ09312B amplifiers. Both MMICs are optimized for exceptional 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 tuned to support multiple UMTS frequency bands. For example, the MMZ09312B demonstrates +29.6dBm output power at 1dB (P1dB) compression from 700 to 1000MHz. The MMZ25332B features +33dBm P1dB from 2300 to 2700MHz. In addition, two Freescale low noise amplifiers, the MML09211H and MML20211H, are included on the radio board.
The company also offers its VortiQa LTE Layer 1 software stack for small cell base stations. Pricing and availability The BSC9131RDB QorIQ Qonverge reference design board is available for $900 (USD). Priced at $1,700 (USD), the RF radio board is part number PSC913XRFBD-XXYY, with “XX” and “YY” representing bands supported. More Information Product web page
