F0109
Dual Path Ultra-Low Noise Amplifier 650MHz to 1000MHz
The F0109 is a dual-path 650MHz to 1GHz high
gain/ultra-low noise amplifier used in receiver
applications.
Features
• RF range: 650MHz to 1000MHz
o F0110: 1500MHz to 2300MHz
o F0111: 2500MHz to 2700MHz
• 18dB typical gain at 850MHz
• 0.5dB typical NF at 850MHz
• 40dBm typical OIP3 at 850MHz
The F0109 LNA is operated as a balanced amplifier
where the inputs and outputs are combined using
external 90° couplers and provides 18dB of typical
gain with 0.5dB of typical noise figure and 40dBm
OIP3 performance. The device uses a single 5V
supply and 115mA typical of total ICC.
• 50Ω single-ended input/output impedances
• +5V power supply
The F0109 is packaged in a 4 × 4 mm, 16-VFQFPN
with 50Ω single-ended RF input and output
impedances for ease of integration into the signal
path.
• ICC = 58mA per channel
• Independent channel standby modes for power
savings
Competitive Advantage
• 1.8V logic standby control
• Ultra-low noise performance of 0.5dB over wide
bandwidths improves receiver sensitivity
• Operating temperature (TEP) range: -40°C to
+105°C
• High gain and linearity
• 4 × 4 mm, 16-VFQFPN package
Applications
• 3G, 4G, 5G wireless infrastructure
• Public safety infrastructure
• General purpose RF
