TYPICAL CHARACTERISTICS OF THE GP2010 GPS RECEIVER RF FRONT-END

The GP2010 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.

NOTE:- ALL Measurements at Vcc = +2.65V made with VCO voltage-regulator DISABLED.
