General Description
The HMC398QS16G & HMC398QS16GE are single
chip GaAs InGaP Heterojunction Bipolar Transis-
tor (HBT) MMIC VCOs. The HMC398QS16G &
HMC398QS16GE 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 per-
formance. The HMC398QS16G & HMC398QS16GE
require no external components
