Overview
The HMC598 is a x2 active broadband frequency multiplier chip developed by Analog Devices Inc. It utilizes GaAs PHEMT technology, making it ideal for various high-frequency applications. When driven by a +5 dBm signal, the multiplier provides a typical output power of +15 dBm across the frequency range of 22 to 46 GHz. This component is particularly useful in reducing the parts count in traditional design approaches, especially in LO multiplier chains for Point-to-Point and VSAT radios.
