B140MB4S Evaluation Board

Introduction

The Knowles Dielectric Labs DEB-B140MB4S is an RF evaluation board for assessing the B140MB4S surface-mount band-pass filter. It is intended for development work around 14 GHz SATCOM-band filtering, providing a dedicated platform for examining the filter in an RF design context.

The board is technically relevant for designs that need to evaluate a compact surface-mount filter while considering operation across a wide stated temperature range of -55°C to +125°C.

What it does

The DEB-B140MB4S supports evaluation of the Knowles Dielectric Labs B140MB4S band-pass filter at 14 GHz. The underlying filter is described as using low-loss, temperature-stable materials, making the board relevant to RF development activities where filter behavior and temperature range are important considerations.

As an evaluation board rather than a finished radio subsystem, it is intended to help engineers assess the B140MB4S filter for integration into a suitable 14 GHz RF signal path.

Applications

• Evaluation of 14 GHz SATCOM-band RF filtering
• RF prototype development using the B140MB4S surface-mount band-pass filter
• Filter assessment during SATCOM front-end or signal-chain design
• Laboratory investigation of filter operation across the stated -55°C to +125°C temperature range

Design considerations

The DEB-B140MB4S is specifically associated with the B140MB4S surface-mount band-pass filter, so it is most relevant where that filter is under consideration for a 14 GHz design. System designers should account for the intended 14 GHz operating frequency and evaluate the filter within the wider RF chain, including the surrounding circuitry and intended operating environment.

The stated -55°C to +125°C operating temperature range is also a useful consideration for development work targeting equipment exposed to broad temperature variation.
