HMC732LC4B Model Information

Model Overview

• Model Number: HMC732LC4B
• Frequency Range: 6 - 12 GHz
• Package Type: 24 Lead Ceramic 4x4 mm SMT Package
• Operating Temperature Range: -40°C to +85°C
• General Description
  The HMC732LC4B is a wideband MMIC Voltage Controlled Oscillator (VCO) that integrates the resonator, negative resistance device, and varactor diode. It offers excellent output power and phase noise performance over temperature due to its monolithic construction. The Vtune port accepts an analog tuning voltage from 0 to +23V. The HMC732LC4B operates from a single +5V supply, consumes only 57 mA of current, and is housed in a RoHS compliant SMT package. This wideband VCO uniquely combines the attributes of ultra-small size, low phase noise, low power consumption, and wide tuning range.
