The 87104A/B/C SP4T and 87106A/B/C SP6T terminated multiport switches provide the life and reliability required for automated test and measurement, signal monitoring, and routing applications. Innovative design and careful process control creates switches that meet the requirements for highly repeatable switching elements in test instruments and switching interfaces. The switches are designed to operate for more than 10,000,000 cycles. The exceptional 0.03-dB insertion loss repeatability is warranted for 5 million cycles at 25 °C.
