Irvine CA (SPX) Oct 24, 2005
U-Nav Microelectronics has announced commercial availability of the DigitalGPS uN1510 RF Macro component. The uN1510 is a complete RF subsystem for down-converting L1 GPS signals to a low-IF I/Q output.

According to Tim Jackson, VP Marketing, "The uN1510 is another example of u-Nav's efforts to further simplify the development of small form-factor GPS receivers. Eliminating the challenging RF design and layout results in faster time to market and reduced development cost. In terms of the customer's manufacturing, the uN1510 simplifies logistics, reduces component inventory and assembly time, and improves production yields."

The DigitalGPS concept is designed to significantly reduce the RF development requirements in GPS applications by offering the GPS RF functionality in an easy to use surface mount component.

DigitalGPS System Design

The uN1510 provides an AC-coupled RF input that can be directly connected to either a passive or active external antenna. An external frequency reference source (typically a TCXO) is used to generate the LO. The uN1510 provides a 2-bit I/Q output that seamlessly interfaces to u-Nav's family of GPS processor Ics including the uN8130 and the uN2110.

Ultra Small Size

The uN1510 is provided in a 5mm x 7mm x 1.8mm surface mount LGA package. When combined with the uN2110 GPS baseband IC, a complete GPS receiver can be implemented in an area of less than 144 sq mm using only four key components (uN1510, uN2110, TCXO, optional RTC crystal.)

U-Nav also provides chip-scale package options for the uN8130 Baseband IC, as well as stacked flash packaging in the form of the uN2110 Baseband IC.
