June, 17 2002 STB7102, STB7103, STB7104 0.1/2.5 GHz Si MMIC BUFFER AMPLIFIERS SOT323-6L (SC70)

DESCRIPTION

The STB7102, STB7103 and STB7104 designed for Mobile Phone applications (0.1/2.5GHz), are an high isolation Si MMIC Buffer Amplifiers. Manufactured in the third generation of ST proprietary bipolar process, they offers an excellent isolation and a good linearity using a low current consumption. These low current amplifiers operate on 3.0 V. The STB710x family is housed in an ultra miniature package SOT323-6L surface mount package. SOT323-6L dimensions are 1.15mmx1.8mm with 0.8 mm thickness. APPLICATION UHF BUFFER AMPLIFIER for Mobile Phone Application (0.1/2.5GHz) ABSOLUTE MAXIMUM RATINGS Symbol Parameter Conditions Value Unit Vcc Supply voltage 3.3 V Tstg Storage temperature -40 to +100 oC Ta Operating ambient temperature -30 to +85 oC
