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 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 5-pin SOT551A plastic SMD package for

low voltage medium power applications.
