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.
