KBA-20+

Overview

The KBA-20+ is a surface-mount frequency doubler manufactured by Mini-Circuits. It operates within a frequency range of 1.6 GHz to 4.8 GHz, effectively doubling the input signal frequency. The component features a nominal coupling of 20 dB and a mainline loss of 2 dB. It supports up to 2 W of power handling capability. The device utilizes an MCLP-4 package for SMD/SMT installation. It functions as a general-purpose RF IC designed for harmonic generation applications in microwave circuits.

Procurement Notes

Verify the specific datasheet version for the KBA-20+ to confirm electrical parameters against current production standards. Ensure that the application environment remains within the specified 1.6 GHz to 4.8 GHz operational range. Confirm that the required power levels do not exceed the 2 W limit. Check compatibility with the MCLP-4 footprint during PCB layout. Validate thermal management requirements for continuous operation at maximum power.

Selection Notes

Select the KBA-20+ when a fixed frequency doubling function is required between 1.6 GHz and 4.8 GHz. This component is suitable for designs needing 20 dB coupling with low mainline loss. Consider the surface-mount package for automated assembly processes. Evaluate the 2 W power rating against system signal levels. Compare performance metrics with alternative multipliers if broader bandwidth or different coupling values are necessary.
