802.11ac Wi-Fi chipsets integrate 2.4 GHz and 5 GHz power amplifiers
With radio, baseband and PA all contained on a single die, the MT7612x solutions deliver higher speed, better range and lower power consumption at minimum BOM cost, all of which are crucial for today’s high volume dual-band AP routers, USB dongles and broadband devices.
The MT7612x chipsets feature dual-band 2.4 GHz and 5 GHz radios with integrated PA, LNA and T/R switches and support up to 867 Mbps of physical layer data rate (256 QAM), offering performance of near 600 Mbps throughput for bandwidth-intensive applications, such as smooth HD video viewing and low latency online gaming.
Complete with MediaTek’s field proven Beam-Forming technology , the chipsets are furthermore capable of intelligently determining a receiver’s distance and location, controlling various transmission parameters, and optimizing the Wi-Fi signals to maximize throughput and range throughout the home.
Also beneficial for the home are the MT7612x chipsets’ Multi Channel Concurrent (MCC) and Dynamic Radio Control features, which help maximize performance in complex indoor environments. Moreover, the chipsets can be augmented with Wi-Fi offload intelligent NIC (iNIC) functionality that allows manufacturers to easily incorporate wireless connectivity into products that previously lacked such capability, thus eliminating the need to upgrade host processors.
Sample MT7612x solutions will be available this quarter, with high-volume production commence in Q3, 2013. The product will be offered in two versions, the MT7612E, which offers a PCIe 2.0 interface, and the MT7612U, which offers a USB 3.0 interface.
Key highlights include calibration free connectivity to lower manufacturing costs; explicit and implicit Beam Forming for transmission and receiving; low density parity check (LDPC) capability; space-time block code (STBC) capability; 256 QAM for higher throughput and better spectral efficiency; per packet/per client radio control for optimal multi-client performance; and multi-channel concurrent fast switching.
