The HMC587LC4B is a wideband GaAs InGaP Voltage Controlled Oscillator which incorporates the resonator, negative resistance device and varactor diode. Output power and phase noise performance are excellent over temperature due to the oscillator"s monolithic construction. The Vtune port accepts an analogue tuning voltage from 0 to 18V. The device operates from a single 5V supply, consumes only 55mA 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.
