General Description
The HMC398QS16G is a single chip GaAs
InGaP Heterojunction Bipolar Transistor (HBT)
MMIC VCO. The HMC398QS16G integrates a
resonator, negative resistance device, varac-
tor diode and divide-by-8 prescaler. The VCO’s
phase noise performance is excellent over tem-
perature, shock, and process due to the oscilla-
tor’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. The HMC398QS16G requires no
external components
