SW-428 Frequently Asked Questions (FAQ)

  • A good PCB layout for the SW-428 should ensure that the input and output stages are separated, with the input stage located near the input connector and the output stage near the output connector. Additionally, a solid ground plane and proper decoupling of the power supply are crucial for minimizing noise and electromagnetic interference.

  • The choice of input and output connectors for the SW-428 depends on the specific application and the type of signals being transmitted. Common connectors used with the SW-428 include BNC, SMA, and N-type connectors. Ensure that the connectors are rated for the frequency range and power handling required by your application.

  • The SW-428 is typically rated for operation from -20°C to +70°C. However, it's essential to consult the datasheet and manufacturer's recommendations for specific temperature ratings, as some versions may have extended temperature ranges or special requirements.

  • The SW-428 is a commercial-grade product, but Stancor offers versions with enhanced screening and testing for high-reliability and military applications. These versions may have additional certifications, such as MIL-PRF-39007 or MIL-STD-202, and should be specified accordingly.

  • To troubleshoot issues with the SW-428, start by verifying the input signal quality, power supply voltage, and PCB layout. Check for signs of overheating, such as excessive temperature or reduced output power. Consult the datasheet and application notes for guidance on troubleshooting and repair procedures.
