Functional Diagram
General Description
The HMC398QS16G & HMC398QS16GE are single
chip GaAs InGaP Heterojunction Bipolar Transistor (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 performance. The HMC398QS16G & HMC398QS16GE
require no external components

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and backside ground slug should be
connected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
