DESCRIPTION
The STB7102, designed for RF Mobile Phone
applications (0.5/2.5GHz), is an high isolation
Local Oscillator Buffer Amplifier. Manufactured in
the third generation of ST proprietary bipolar
process, it offers an excellent isolation and a good
linearity using only 4mA current consumption. The
STB7102 is housed in an ultra miniature package
SOT323-6L surface mount package.
