Notes:
• As a combiner of noncoherent signals, max. power per port is power rating divided by number of ports.
• Operating temperature: -55°C to 90°C
Storage temperature: -55°C to 100°C;
• Over -55°C to +55°C. Derate linearly to 20% of rating at 90°C.
• General Quality Control Procedures and Environmental Specifications are given in Mini-Circuits Guarantees Quality.
Hi-Rel, MIL description are given in Hi-Rel and MIL
• Prices and Specifications subjects to change without notice.
