Board Overview

This SP4T board integrates the a solid state switch die with an optimized RF layout to support ultra wide band, multi-GHz operation. It includes 2.92mm female connectors and control interfaces to make integration into larger systems straightforward:

• RF Interfaces: 50 Ω 2.92 mm female connectors (board level)
• Control: 3.15 V – 3.45 V CMOS logic compatible
• Power Supply: Single 3.3 V supply for switch IC rail

The board implements proper RF grounding, impedance control, and decoupling to maximize isolation and minimize reflections across the operating band.

Software & Control

• Control Method: Logic pins for switching states
• Automation Support: GPIO / USB support (via host micro/controller).
• Switch Commands: Set active path; Disable all paths; Read state

This board can be easily integrated with Python or embedded control software.
