The F0109 is a dual path 650MHz to 1GHz High Gain / Ultra-Low Noise amplifier used in receiver applications.
The F0109 LNA is operated as a balanced amplifier where the inputs and outputs are combined via external 90° couplers and provides 18dB of gain. The device uses a single 5V supply and 120mA typical of total ICC.
The F0109 is packaged in a 4 x 4 mm, 16-pin VFQFPN with 50Ω single-ended RF input and output impedances for ease of integration into the signal path.
