Full Band – Compact Isolators

Available in K-J Bands, WR-42 to WR-3

Description:

Mi-Wave’s 116 Series Full Band Compact Isolator uses the Faraday principle of rotation in a broadband dielectric waveguide design to achieve high isolation across full waveguide bands. High-quality ferrite material is used in these isolators, and the magnetic field is produced by an integral permanent magnet. To ensure maximum reproducibility and performance, a combination of precise machining operations and refined assembly techniques are used.

RF Isolators

An RF Isolator is a two-port device that protects RF components in a system from excessive signal reflection. It is a non-reciprocal device that ensures all the power is transmitted from port 1 to port 2, while isolating absorbing/isolating any power incident at port 2. An isolator is often placed in front of a sensitive component in the Rx/Tx chain to avoid unwanted signals from damaging sensitive components.

An isolator is a two-port device that transmits microwave or radio frequency power in one direction only. Due to internal behavior, propagation in one direction is allowed while the other direction is blocked. The non-reciprocity observed in these devices usually comes from the interaction between the propagating wave and the material, which can be different with respect to the direction of propagation.  See more here

Selecting RF Isolators

When selecting an RF Isolator, knowing the parameters you need to specify is important. Below are a list of the key parameters to look out for when selecting an isolator:

Isolation (dB): The level of Isolation from the output port to the input port. The higher the isolation the better the components are protected.

Insertion Loss (dB): The signal loss from port 1 to port 2.

Power (W): This is the power level that the isolator can handle while maintaining its electrical characteristics. The forward power is the level of power that the isolator can handle an incident at port 1. The reverse power is the level of power incident at port 2 that the isolator can absorb.

Compact Size Isolators

Our wideband compact isolators are for the spectrum in the millimeter wave range of frequencies from 18 to 325 gigahertz (GHz).

Designed for full waveguide band operation, the 116 series isolator is used in swept frequency applications. These components provide a high degree of isolation between signal sources and mismatched loads by attenuating the reflected signals. The insertion loss in the forward direction is minimized to allow for the full available power from the signal source-isolator combination.

Typical applications for these broadband isolators include laboratory setups as well as millimeter wave test sets and automotive radar.

The unique feature of these isolators is the reduced size footprint then normal isolators.
