New Waves: Industrial, Scientific and Medical Applications

Solid-state Amplifiers

RS 216AR RF/Microwave Instrumentation’s new solid-state amplifier family covers the 8 to 20 GHz frequency range. Model 5S8G20A offers 5 W of power and model 20S8G20A provides 20 W. Both models are perfect for EMC and wireless testing. Like the other members of the “S” Series amplifiers, both models are extremely tough, durable and are full Class A. They have superior linearity and they are 100 percent VSWR tolerant. Even when mismatch is severe, AR’s “S” Series amplifiers will not fold-back or shut down. They continue to deliver 100 percent of the rated power to the load.

Software and Foundry Process

RS 241A catheter developed by Meridian Medical Systems (MMS) simultaneously delivers microwave radiation for tissue heating and directly senses the temperature of the heart wall using a radiometer remote sensing device fabricated as a microwave monolithic integrated circuit (MMIC). The MMIC was designed using AWR's Microwave Office® high-frequency EDA software and transferred to TriQuint Semiconductor's foundry using a process design kit (PDK) developed jointly by AWR and TriQuint.
