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
1
1
d
Bm 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.

List of Materials for Evaluation PCB 104713
[1]
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.
