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.

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.
