7002

STB7002 1.8GHz THREE GAIN LEVEL LNA • FULLY INTEGRATED 1.8GHz LNA • THREE GAIN LEVELS (0dB, 18dB, 26dB typ. @ 2.8V) • LOW NOISE FIGURE • TEMPERATURE COMPENSATED APPLICATIONS • DCS HANDSETS ORDER CODE STB7002 MSOP8-EP (exposed pad) BRANDING 7002 DESCRIPTION The STB7002 is a Silicon monolithic amplifier, that offers low noise figure and three gain levels for 1.8GHz applications. STB7002 is housed in a small industry-standard MSOP8-EP surface mount package, requiring very little board space (50% reduction vs SO8 Package). MSOP8-EP dimensions are 3mmx5mm with a 1.1mm thickness. STB7002 is ESD protected and requires minimum external components in the application circuit, for the on-chip bias and gain control. Furthermore, temperature and supply voltage compensation ensures high stability over a wide range of operating conditions.
