This page provides basic information about E Band Isolators and W Band Isolators, including a table listing manufacturers for both.

E Band Isolator

E Band Isolator

The E Band covers frequencies from 60 to 90 GHz and is also known as the WR12 Band. Figure 1, shown above, illustrates an E Band Isolator from SAGE Millimeter, Inc.

When selecting an E Band Isolator, consider these typical specifications:

  • Frequency Range: 60 GHz (Minimum) to 90 GHz (Maximum)
  • Insertion Loss: Approximately 1.5 to 2 dB
  • Isolation: 28 dB
  • Return Loss: 14 dB
  • Power Handling: 1.2 W to 1.5 W (CW)

W Band Isolator

W Band Isolator

The W Band spans the frequencies from 75 to 110 GHz and is referred to as the WR10 Band. Figure 2, shown above, depicts a W Band Isolator from Micro Harmonics, Fincastle, VA.

Key specifications to consider when choosing a W Band Isolator include:

  • Frequency range: 75 to 110 GHz
  • Insertion loss: Approximately 1.4 to 2.1 dB
  • Isolation: Approximately 25 dB
  • VSWR: 1.4:1
  • Power Rating: 1 Watt (Max.)
