Philips Semiconductors Preliminary specification
MMIC variable gain amplifier BGA2031
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 poweramplifiers 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 5-pin SOT551A plastic SMD package for
low voltage medium power applications.
