Overview
The HMC391LP4 and HMC391LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) Monolithic Microwave Integrated Circuit (MMIC) Voltage-Controlled Oscillators (VCOs) produced by Analog Devices Inc. These VCOs are integrated with resonators, negative resistance devices, varactor diodes, and buffer amplifiers. They operate within the frequency range of 3.9 GHz to 4.45 GHz, offering excellent phase noise performance across various temperatures, shock, and vibration conditions due to their monolithic structure.
The devices are packaged in a low-cost leadless QFN 4 x 4 mm surface mount package, making them suitable for a variety of RF and microwave applications. The VCOs are powered by a single supply of +3V at 30 mA and provide a typical output power of +5.0 dBm.
