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.
The HMC358MS8G is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC Voltage Controlled Oscillator (VCO) that integrates a resonator, negative resistance device, varactor diode, and buffer amplifier. It is designed for C-Band applications such as UNII & Pt. to Pt. Radios, 802.11a & HiperLAN WLAN, and VSAT Radios. The device operates from a single 3V supply and is packaged in a low-cost, surface-mount 8-lead MSOP package with an exposed base for improved RF and thermal performance.
