fci_block_diagrams_no1_fc104.svg

The FCF104 is a front-end low noise amplifier (LNA) for LTE receiver applications. It covers the frequency range from 716 MHz to 960 MHz. The LNA has a high gain mode and bypass gain mode. It operates from 1.5V to 3.3V supply voltage. In the high gain mode, the LNA provides 15 dB gain, 0.7 dB NF (noise figure), 4.4 dBm in-band IIP3 (input 3rd order intercept point) at a current consumption of 5.4 mA. In the bypass gain mode, the LNA provides -2 dB gain, 2 dB NF, 26.7dBm IIP3.
