Philips Semiconductors
MMIC variable gain amplifier
Preliminary specification
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.
