HMC358MS8G / 358MS8GE v04.0607 MMIC VCO w/ BUFFER AMPLIFIER, 5.8 - 6.8 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Ampl ifier Pout: +11 dBm for C-Band applications such as: Phase Noise: -110 dBc/Hz 100 KHz UNII & Pt. to Pt. Radios No External Resonator Needed 802.11a & HiperLAN WLAN Single Supply: 3V 100 mA VSAT Radios 2 15mm MSOP8G SMT Package Functional Diagram General Description The HMC358MS8G & HMC358MS8GE are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC358MS8G & HMC358MS8GE inte- 11 grate resonators, negative resistance devices, varac- tor diodes, and buffer ampl ifiers. The VCOs phase noise performance is excellent over temperature, shock, and process due to the oscillators 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.
