HMC584LP5 Application field and Working principle

The HMC584LP5 is a microwave component from the RF Misc ICs and Modules family. It is a 5-bit De-Rotator with four independent paths for signal transmission. The component is used in the fields of SONAR, RADAR, receivers, and sophisticated hi-tech defense electronics.The device operates through a dual-conversion architecture, using a bank of 5-variable attenuators for controlling signal de-rotation. The architecture consists of two different stages of frequency conversion wherein the second stage takes the signal in the form of a quadrature signal. The quadrature signal is processed by multiple paths of variable attenuation before being inputted to the output pins. HMC584LP5 is equipped with an enhanced channel-to-channel isolation. This ensures that the output signals received are not interfered with by noise or any unwanted signal. This high component isolation also helps in maintaining signal integrity and enhancing the reliability of the device.The component has a frequency range of 5GHz to 6GHz and a precise linearity of less than 1 dB in the operating frequency range. It has an input voltage ranging from 1.8 to 3.3 V along with an output DC voltage of up to 3 Volts. Its output impedance is 50 Ohms and is optimized for use with standard connector interfaces.The working principle of the HMC584lp5 can be understood in the following diagram:

In the above diagram, the output signal of the Low Noise Amplifier is first fed into the Mixer. The first conversion process takes place here and the IF frequency is generated at the output of the mixer.The IF frequency is then fed through Variable Attenuation paths, which are responsible for the de-rotation of the signal. This is the primary job of the HMC584LP5. The output of the Variable Attenuators is then fed to the second mixer, which performs the second conversion process and the desired output signal is derived from the second mixer.The HMC584LP5 is optimized for use in different application fields such as receivers, RADARs, SONARs and defense electronics. This component brings reliability and enhanced performance to the applications in which it is used.
