The HMC561LP3ETR with RF Wireless Misc x2 Active mult SMT, 8 - 21 GHz Fout manufactured by Analog Devices is a double-balanced active multiplier that is designed to operate in the 8 - 21 GHz frequency range. It is designed for use in high-frequency, high-power applications such as radar transmitters, point-to-point radios, and instrumentation applications. This device is constructed from a monolithic chip which contains a low-noise amplifier and a pair of diodes to provide inherent gain and power regeneration. This reduces the need for external components and reduces the area of the layout. The device features excellent linearity, making it ideal for use in complex RF systems, and is capable of withstanding high-power inputs. In addition, it is RoHS compliant.
