The HMC358MS8G is a single supply, low noise, high frequency VCO from Hittite. It integrates a resonator, negative resistance device, varactor diode, and buffer amplifier. It is manufactured using GaAs InGaP hetero-junction Bipolar Transistor (HBT) technology, and therefore exhibits excellent phase noise performance over temperature, shock, and process. The voltage controlled oscillator is packaged in a low cost, surface mount 8 lead MSOP package with an exposed base for improved RF and thermal performance.
