DEB12054 Development Board

Introduction

The Dielectric Laboratories / Knowles DEB12054 is an RF diplexer development board for evaluating the ADP12054 surface-mount diplexer. It provides a dedicated evaluation platform for a component intended for satellite-communication frequency bands centered at 11.75 GHz and 19.25 GHz.

What it does

A diplexer separates or combines signals in two frequency bands, allowing distinct RF paths to share a common signal connection. The DEB12054 is designed specifically to support assessment of the ADP12054 diplexer in Satcom-band designs.

The board targets the ADP12054’s two stated band centers:

• 11.75 GHz
• 19.25 GHz

The associated ADP12054 diplexer is specified for operation across a -55°C to +125°C temperature range, making temperature-range evaluation relevant where the end application is expected to encounter environmental extremes.

Applications

Potential uses that follow directly from the board’s function include:

• Evaluation of ADP12054 diplexer behavior in 11.75 GHz and 19.25 GHz RF signal paths
• Satcom-band RF prototyping
• Bench development of circuits that need to separate or combine the two stated frequency bands
• Temperature-range assessment of designs using the associated diplexer

Design considerations

The DEB12054 evaluates a surface-mount diplexer, so it can be useful when moving from component-level RF evaluation toward a design that will incorporate the ADP12054 in a surface-mount assembly. Designers should account for both stated Satcom-band center frequencies and the associated diplexer’s -55°C to +125°C operating-temperature specification when determining whether the evaluated component is appropriate for their intended RF environment.
