STB7102
0.5/2.5 GHz LO BUFFER AMPLIFIER
OPERATING FREQUENCY 500-2500MHz
LOW CURRENT CONSUMPTION (4mA @ 2.7V)
EXCELLENT ISOLATION (43dB @ 850MHz)
INPUT AND OUTPUT RETURN LOSS > 15dB
ULTRA MINIATURE SOT323-6L PACKAGE
(1.15 x 1.8 x 0.8 mm)
PRELIMINARY DATA
SOT323-6L (SC70)
DESCRIPTION
The STB7102, designed for RF applications (0.5/
2.5GHz), is a high isolation Local Buffer Amplifier.
Manufacturated in the third generation of ST propri-
etary bipolar process, it offers an excellent isolation
(43dB) and a good linearity using only 4mA of cur-
rent consumption. STB7102 is housed in a ultra-
miniature package SOT323-6L surface mount
package, requiring very little board space (50% re-
duction vs SOT143 Package).
SOT323-6L dimensions are 1.15mmx1.8mm with a
0.8mm thickness.
APPLICATION
UHF LO BUFFER AMPLIFIER for CDMA standard.
