mmWave Isolator basics and types | 5G mmwave Isolator
This application note covers mmwave Isolator basics, specifications and types. It mentions features of 5G mmwave Isolators from popular manufacturers.
What is mmwave Isolator?
• Isolator is a non-reciprocal device which passes electromagnetic (EM) signals only in one direction and absorbs EM Waves in the opposite direction.
• The Isolators which operate in the mmwave frequency ranges are known as mmwave Isolators.
• Millimeter frequency spans from 30 GHz to 300 GHz. These frequencies are used for various applications such as millimeter wave imaging, mm wave scanner, medicine, radar, 5G cellular etc.
• Mmwave bands used in 5G wireless technology are listed in the table below.
The mmwave Isolator types include Faraday Rotation Isolator, Cryogenic Isolator and Drop-In Isolator
based on their design and construction. Following specifications are considered before selecting the mmwave Isolator
for the desired applications.
• Flange Type (EIA)
• Frequency Band (GHz)
• Insertion Loss (dB)
• Isolation (dB)
• Max.Power (Watt)
