Overview
The HMC577LC4B is a x2 active broadband frequency multiplier produced by Analog Devices Inc. This component utilizes GaAs PHEMT technology and is packaged in a leadless, RoHS compliant SMT (Surface Mount Technology) package. It is designed to operate within the frequency range of 27 to 31 GHz, making it suitable for various high-frequency applications.
The multiplier is driven by a +5 dBm signal and provides a typical output power of +20 dBm. It features high Fo and 3Fo isolations, exceeding 55 dBc at 29 GHz, and low additive SSB Phase Noise of -128 dBc/Hz at 100 kHz offset. This ensures good system noise performance and makes it ideal for use in LO multiplier chains for point-to-point and VSAT radios.
