Functional Diagram
General Description
The HMC401QS16G & HMC401QS16GE are GaAs
InGaP Heterojunction Bipolar Transistor (HBT) MMIC
VCOs. The HMC401QS16G & HMC401QS16GE
integrate resonators, negative resistance devices,
varactor diodes and divide-by-8 prescalers. The
VCO’s phase noise performance is excellent over
temperature, shock, and process due to the oscillator’s
monolithic structure. Power output is -7 dBm typical
from a 5V supply voltage. The voltage controlled
oscillator is packaged in a low cost, surface mount
16 leaded QSOP package with an exposed base for
improved RF and thermal performance.
