LTE small cell processors boast AKM's latest RF transceiver
Asahi Kasei Microdevices (AKM) Corp. has unveiled its complementary LTE small cell radio transceiver and Cavium's integrated LTE small cell processors. AKM's RF transceiver products claim to enable LTE small cell makers to offer mobile operators with industry-leading performance within the low power budgets they require. AKM has worked closely with Cavium to enable their innovative small cell design with the AKM transceiver.
The AKM AK1589 is an FDD-LTE/TD-LTE/WCDMA/TD-SCDMA single-chip RF transceiver that provides ultra-low power consumption, 800mW at 10MHz bandwidth and 1W at 20MHz bandwidth, with 2Tx2Rx MIMO. It offers single ended transmitter outputs and independent sniffer ports permitting users to simplify the front end design. In addition, the AK1589 can also support TD-SCDMA and TD-LTETM applications
The AKM AK1587 is an FDD-LTE-A/TD-LTE-A/FDD-LTE/TDD-LTE/WCDMA RF transceiver providing a highly integrated solution of 4Tx4Rx MIMO or two Carrier Aggregation (CA) channels in a single chip. Also included on-chip are two built-in TX and RX LO blocks. A single AK1587 chip can support 2x2 MIMO configurations for inter-band CA, intra-band non-contiguous CA, intra-band contiguous CA, LTE/WCDMA dual mode, or 4x4 MIMO configurations for single Carrier Component (CC). The AK1587 is equipped with JESD204B as well as LVDS and LVCMOS interfaces. JESD204B can be connected through 2 lanes/1 lane configuration. The AK1587 also implements Crest Factor Reduction (CFR) circuitry, effectively reducing the Peak-to-Average Power Ratio (PAPR) allowing the power amplifiers to run with less back off, resulting in higher power efficiency and lower system cost. AK1587 will be sampling 2Q14 with mass production planned in 1Q15.
