DC to 6 GHz Switches Offer High Power
Design Flexibility
KCB’s latest SPST through SP6T switches are ready for your high power-handling requirements
Standard high

mount (SMT)
package
from 20 to 200 Watts. These versatile devices feature the highest power-handling capability
available in standard QFN packages and thermally conductive flange-mount packages. As
an added feature, they’re shipped complete in your choice of multiple factory-configured ports.
Designed and manufactured with PIN diode technology, they’re 100 percent RF tested (small signal), have robust carrier
construction, and are composed with thick deposition thin film traces. They’re housed in standard 5 or 7mm QFN-style
packages, and also in hermetic packages. They’ve been created for applications where robust design/construction and
low costs are key application drivers.
High Power SMT Switches
For power levels up to 100 Watts, the KCB high power surface-mount switch product line provides the designer
Standard high
power package
with AlN carrier and CuW
sub-mount
with a flexible platform from which switches can be tailored to a specific application. With low loss performance from
DC to 6 GHz, and robust construction, these switches are ideally suited for today’s demanding portable military comms
marketplace. KCB offers several off-the-shelf configurations, as well as dozens of possible configurations that can be
quickly realized using off-the-shelf components. In addition, the designer can choose from a menu of diodes that provide
optimal linearity for the application. These features, coupled with KCB’s ability to 100% small signal test, give the engineer the highest level of confidence that the switch will meet its intended application.
High Power Flange Switches
To address the need for switches that can handle powers in excess of 100 Watts, KCB has developed a flanged-based
switch product line. By utilizing an AlN carrier with a CuW sub-mount construction, these products offer superior heat
spreading, which allows for larger CW incident power levels up to 200 Watts. This, coupled with larger minimum breakdown voltages, provides the designer with a switch that is perfected for higher power comms radios, radar, and counter
