GP2015
TYPICAL CHARACTERISTICS OF THE GP2015 GPS RECEIVER RF FRONT-END
The GP2015 has been characterised to guarantee reliable operation over the Industrial Temperature range (-40°C -> +85°C
ambient). This was achieved by setting the device case temperature to extremes of +110°C and -50°C.
The following charts show the typical variation of key parameters across the extended case temperature range.
