Lime Microsystems has started shipping the second generation of its field programmable radio frequency (FPRF) devices.
The fully programmable, low power chips contain dual transceivers that cover the frequency range 0.1 to 3800MHz. In addition, they cover all the cellular bands used in 2G, 3G and 4G networks, as well as many commercial and military bands. "We are delighted to be shipping the LMS7002M devices", said Lime CEO Ebrahim Bushehri. "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." The devices are supported by a Universal Wireless Communications Toolkit (UWCT) and will in the future be supplemented with a number of low cost development boards. Lime says they are suitable for implementing MIMO systems with a digital bandwidth up to 60MHz in each channel. They also include user programmable DSP that can equalise the gain and phase of a MIMO system, or enhance the analogue filtering to provide a lower power consumption.
