FCF102: Front-end IC (Low Noise Amplifier) for Mid/High-band(1452 ~ 1600MHz, 1805 ~ 2690HMz) LTE applications



The FCF102 is a front-end low noise amplifier (LNA) for LTE receiver applications. It covers the frequency range 1452MHz ~ 1600MHz and 1805MHz ~ 2690MHz. The LNA has a high gain mode and bypass gain mode. It operates from 1.5 V to 3.3 V supply voltage. In the high gain mode, the LNA provides 13.6 dB gain, 0.75 dB NF (noise figure), 0.8 dBm in-band IIP3 (input 3rd order intercept point) at a current consumption of 4.7 mA. In the bypass gain mode, the LNA provides -2.6 dB gain, 2.6 dB NF, 25.8 dBm IIP3.
