This RF switching board uses the QPC6044TR13 SP4T RF switch to select between four attenuation paths (0, 12, 24, and 36 dB) or four 10 MHz-centered filter options with bandwidths of 1, 5, 10, and 15 MHz. The attenuation network operates from DC to 3 GHz. A configurable 0 Ω jumper allows selection between attenuation and filter modes. The board features edge-mount 50 Ω SMA connectors for RF input and output.

Long Description

This RF signal conditioning board is built around the QPC6044TR13 SP4T RF switch, providing flexible selection between multiple attenuation and filtering configurations for RF testing and signal processing applications.

The board supports four selectable attenuation paths of 0 dB, 12 dB, 24 dB, and 36 dB, with the attenuation network designed to operate across a wide frequency range from DC to 3 GHz. In addition, the board includes four selectable bandpass filters centered at 10 MHz with bandwidth options of 1 MHz, 5 MHz, 10 MHz, and 15 MHz, enabling configurable signal filtering for narrowband and broadband applications.

Users can switch between attenuation mode and filter mode by installing or removing a configurable 0 Ω jumper, allowing the board to adapt easily to different RF signal chain requirements. RF input and output connections are provided through edge-mount 50 Ω SMA connectors, ensuring reliable high-frequency performance and straightforward integration into test setups and embedded RF systems.
