Page 1
The F1471 is a high linearity RF Driver Amplifier
designed to operate within the 400MHz to 4200MHz
frequency band. Using a single 5V power supply
and only 130mA of I
CQ
, the F1471 provides 15dB of
gain and 3.8dB of noise figure, and 29dBm OP1dB
at 3600MHz.
The F1471 is packaged in a 3 × 3 mm, 16-VFQFPN
package, with matched 50Ω input and output
impedances for ease of integration into the signal
path.
Competitive Advantage
• Excellent linearity maintained over large
bandwidths
• OIP3 lineari t y configur a ble with bi as curr ent
adjustments
• Exceptional OP1dB performance maintained at
low bias currents
• Robust ESD Performance
o 1.5kV HBM ESD rating
o 1kV CDM ESD rating
• Includes on-chip DC overvoltage and RF
overdrive protection
Features
• RF range: 400MHz to 4200MHz
• 15dB typical gain at 3600MHz
