RF Front End (LNA + PA) is the integration of low noise amplifiers and power amplifiers for wireless communication system front end. The SST11LF04-Q3CE is an ideal RF Front End solution, which integrated a current-mode low noise amplifier and a power amplifier in a seven-pin miniature low-cost surface-mount package.

The application fields of the SST11LF04-Q3CE RF Front End include 2.4 GHz ISM and LTE MCS-8, WHDI, WIMAX, UWB and satellite communications. Due to its low noise and low power consumption, it is suitable for long-distance operation in both the receiver and transmitter chain. The device is designed as an easy-to-use, low power consumption, low noise and high reliability RF Front End to meet the increasing demand for high performance and to minimize BoM and interface complexity.

The working of SST11LF04-Q3CE includes a low noise amplifier module which amplifies the received weak signal to an adequate level and improves the signal-to-noise ratio. The power amplifier boosts the amplified signal to a much higher output power, which is needed to overcome the loss in the antenna system. It can improve the transmit power efficiency, which is very important for long-distance communications. In order to optimize the performance of the SST11LF04-Q3CE, the package also has two test points.

The SST11LF04-Q3CE is fully compliant with the 5 V power supply and is ideal for applications which require high performance, low power consumption, low noise and high reliability RF Front End. The device comes with a wideband input/output matching network which can reduce external circuitry. It also has integrated protective circuitry to protect the chip from ESD, input overvoltage, ACS, and transmission-line reflections.

In conclusion, the SST11LF04-Q3CE is a great example of a RF Front End which integrated both low noise and power amplifiers in one package. It is suitable for applications which require a low power consumption, low noise, and high reliability RF Front End. The integrated protective circuit helps protect the device from the environmental factors, as well as external interference. In addition, the wideband input/output matching network reduces the complexity of the external circuitry. The device is suitable for use in converged communication systems, short-range radio links, and broadcast applications.
