RF Amplifiers, such as the HMC564-SX, have a wide range of applications, ranging from industrial, medical, professional, military, and consumer technologies. The HMC564-SX is a high power, high efficiency broadband amplifier designed for use in systems where wide dynamic range, moderate linearity, and robust operation are required. Its design is targeted at applications up to 10 GHz.

The working principle of the HMC564-SX is based on a GaN-based power amplifier architecture with two to four stages that are optimized for maximum efficiency and power. The output stage is capable of pulsed signals up to 500 Watts for a peak-to-average ratio of 10:1. The wide input to output dynamic range and high efficiency make it ideal for peak power requirements or applications such as those in digital and wideband power transmission, communication links, point-to-point microwave systems, and other pulsed applications.

The HMC564-SX is constructed with a dielectric substrate on which chips and components are deposited. The transistor chips connected in series form a power amplifier chain that amplifies low-power input signals to the required output power. The switch at the input is designed to select the appropriate stage, depending on the amplitude of the signal.

The amplifier has a high linearity, offering low out-of-band emission and better dynamic range. The gain flatness, noise figure, and power-added-efficiency of the amplifier are also highly-responsive in order to maximize the performance of the device. The high efficiency design dissipates less than 200 watts of power at 100% load and provides good gain control for a wide range of input power levels.

The HMC564-SX can be tailored to meet specific needs related to gain and impedance matching by the use of external components. This feature provides a more flexible and efficient solution for high power, wide dynamic range, and linearity requirements. The amplifier is also built with a range of protection circuits which monitor the device for thermal, power, and/or harmonic overloads.

The amplifier offers a wide variety of applications, from low power ultra-wideband consumer electronics, Bluetooth® audio and short-range communications, to complex RFIS grids used in military applications. It is also suitable for the ideal requirements of a base station, where high power, high efficiency, and high dynamic range are crucial. Finally, it is ideal for microwave links in WiMAX and backhaul radio systems, offering operational stability and flexibility.
