MMIC VCO w/ BUFFER

AMPLIFIER, 5.5 - 6.1 GHz

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 exposed paddle should be connected

directly to the ground plane similar to that shown. A

sufficient number of via holes should be used to con-

nect the top and bottom ground planes. The evalua-

tion circuit board shown is available from Hittite upon

request.
