RF2472
2.4GHz LOW NOISE AMPLIFIER WITH ENABLE
• TDMA/CDMA PCS LNA
• TDMA/CDMA/FM Cellular LNA
• ISM Band LNA/Driver
• Low Noise Transmit Driver Amplifier
• General Purpose Amplification
• Commercial and Consumer Systems
The RF2472 is a general purpose, low-cost, high-perfor-
mance low noise amplifier (LNA) designed for operation
from a 2.7V to 4V supply with low current consumption.
The device is optimized for 2.4GHz LNA applications, but
is also useful for 1.9GHz PCS, K-PCS, 900MHz ISM
band, 1.5GHz GPS, and 4.9GHz to 5.9GHz WLAN appli-
cations. The RF2472 is available in an industry-standard
SOT23 5-lead surface mount package, enabling compact
designs which conserve printed circuit board space.
• DC to >6GHz Operation
• 2.7V to 4.0V Single Supply
• High Input IP3
• 1.5dB Noise Figure at 2400MHz
• 14dB Gain at 2400MHz
• Low Current Consumption of 6mA at 3V
