Functional Diagram
General Description
The HMC358MS8G & HMC358MS8GE are GaAs
InGaP Heterojunction Bipolar Transistor (HBT) MMIC
VCOs. The HMC358MS8G & HMC358MS8GE inte-
grate resonators, negative resistance devices, varac-
tor 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.
