The LMS7002M, a 2nd gen Field Programmable Radio Frequency (FPRF) device which features dual transceivers that cover the frequency range of 0.1-3800MHz, has been released by Lime Microsystems. Alongside the cellular bands used in 2G, 3G and 4G networks, the programmable, low power chip covers many commercial and military bands. Enabling flexibility, parameters such as gain and filter bandwidth are in-system programmable.

The LMS7002M, which is supported by a Universal Wireless Communications Toolkit (UWCT), will be supplemented with a number of low cost development boards in the future. The UWCT provides users with hardware, software and direct access to expert application engineers. 

The featured dual transceivers allow users to implement MIMO systems with a digital bandwidth up to 60MHz in each channel. A user programmable DSP enables users to equalise the gain and phase of a MIMO system, or enhance the analogue filtering to provide a lower power consumption. When configured for MIMO operation, the chip, which uses a 65nm CMOS process, consumes only 550 in single-in single-out mode or 80mW. The LMS7002M, which requires minimal external components, can operate using a single 1.8V supply rail.

“We are delighted to be shipping LMS7002M devices”, commented Ebrahim Bushehri, CEO, Lime Microsystems. “We have enormous interest from applications spanning small cells, software defined radio, industrial networking, medical, test equipment and high end M2M such as asset tracking. We believe that our pricing strategy will stimulate a range of applications in variety of markets including commercial and military customers.

The LMS7002M is priced at $110 in sample quantities and $63 in 5,000 unit quantities. With the release of the 2nd gen FPRF device, Lime has reduced the price of its 1st gen device, the LMS6002D. The predecessor is priced at $35 in sample quantities and $15 in 5,000 unit quantities.

Customers can download the free design software, a range of development boards and projects directly from the Lime website and MyriadRF, an open-source initiative.
