RF cores target DVB-H, GPS devices

Analog and mixed-signal vendor Chipidea Microelectronica is expanding its RF IP offerings with the release of two cores. The cores are for developers of video-enabled handheld appliances and personal navigation devices.

The first in the company's line of CMOS-based RF platforms is a DVB-H mobile tuner. It enables you to design subsystems for the delivery of DVD-quality video and audio to handhelds.

The other product is an integrated receiver for handheld GPS satellite reception. These two platforms mark the beginning of what will be a portfolio of RF platforms and subsystems from Chipidea.

Both designs are for SoC devices with small footprints and low dissipation. Chipidea's RF platforms provide you with a pre-verified set of RF and mixed-signal approaches that combine optimal analog/digital partitioning with the flexibility to integrate IP into almost any design.

The mobile tuner IP platform enables full-band support with three separate inputs. It covers VHF Band III (176MHz through 245MHz), UHF Band IV and Band V (470MHz through 870MHz), and L-Band (1.45Ghz through 1.685GHz).

The mobile tuner IP platform supports DVB-H, DMB, and ISDB-T standards.

This platform eases design integration with a so-called zero-IF (direct conversion; no intermediate frequency amplifier strip) architecture; no external filters are required either. With very dissipation, and an extremely small chip area, this platform is slated for portable consumer electronics where cost and battery life are paramount.

With a first-generation implementation already in silicon, Chipidea's DVB-H platform is now available.

The company's GPS IP is a receiver for GPS L1 band, replete with a low-noise amplifier (LNA). Its low-IF architecture requires no external IF filters. Like the DVB-H platform, this is a low power system using a small chip area.

The first-generation of this IP is already in silicon. Future versions will incorporate a more flexible topology for supporting both Galileo and Glonass birds.

Aside from consumer applications, Chipidea also offers a professional multi-band version for full-featured Galileo. It's now in fabrication.

Chipidea plans to expand its RF IP offerings to include packages for UWB front-ends, wireless sensor networks, and embedded transceivers in nanometer feature-sized SoCs.

Chipidea also has an RF design team of more than 20 engineers. They're willing to do what it takes to see that your integration process is successful, all the way through to system validation.
