FCF101: Front-end IC (Low Noise Amplifier) for Low-band(716 ~ 960MHz) LTE applications



The FCF101 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), 0 dBm in-band IIP3 (input 3rd order intercept point) at a current consumption of 5.5 mA. In the bypass gain mode, the LNA provides -2.2 dB gain, 2.2 dB NF, 26 dBm IIP3.




Frequency range: 716 ~ 960MHz

High gain mode: 15dB Gain, 0.7dB NF, 0dBm IIP3

Bypass mode: -2.2dB Gain, 2.2dB NF, 26dBm IIP3

Only one inductor is need for input matching

No external component is need for output matching

Supply voltage: 1.5 ~ 3.3V
