MMIC variable gain amplifier
FEATURES
High gain
Excellent adjacent channel power rejection
Small SMD package
Low dissipation.
APPLICATIONS
General purpose variable gain amplifier for low voltage
and medium power
Driver for power amplifiers in systems that require good
linearity, such as CDMA, both cellular band (850 MHz)
and PCS (1.9 GHz). This is because of the high output
power and good linearity.
DESCRIPTION
Silicon Monolitic Microwave Integrated Circuit (MMIC)
2 stage variable gain amplifier in double polysilicon
technology in a 6-pin SOT363 SMD plastic package for low
voltage medium power applications.
