RF Front End ICs

Analog Devices offers RF Front End ICs for phased array antenna solutions. These RF Front End ICs are placed right at the antenna element and can quickly switch between transmit and receive functions in radar applications. The power amplifier on the transmit side is highly efficient operating in short pulse durations. The low noise amplifier on the receive side has a low noise figure with high linearity so that it won’t distort the incoming return signal. The RF Front End IC also incorporates a high performance switch to toggle between the transmit and receive paths. Highly integrated planar phased array antennae need small form factor solutions, and Analog Devices has integrated the switch, low noise amplifier, and power amplifier into a small surface mount package as well as the decoupling capacitors, providing an optimal solution.
