HMC358MS8G / 358MS8GE v04.0607 MMIC VCO w/ BUFFER AMPLIFIER, 5.8 - 6.8 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifier for C-Band applications such as: Pout: +11 dBm • UNII & Pt. to Pt. Radios No External Resonator Needed • 802.11a & HiperLAN WLAN Single Supply: 3V @ 100 mA • VSAT Radios 15mm2 MSOP8G SMT Package Functional Diagram General Description Phase Noise: -110 dBc/Hz @100 KHz The HMC358MS8G & HMC358MS8GE are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC358MS8G & HMC358MS8GE integrate resonators, negative resistance devices, varactor diodes, and buffer amplifiers. The VCO’s phase noise performance is excellent over temperature, shock, and process due to the oscillator’s monolithic structure. Power output is 11 dBm typical from a 3V supply voltage. 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.
