Co-axial Isolators and Circulators

MESL Microwave has redesigned and improved their range of stripline co-axial isolators that operate in the 300MHz to 20GHz range. Using a modular design approach these parts offer improved microwave performance with typical Insertion Loss of 0.3dB and isolation of 23dB for a 15% bandwidth device.

The parts are ideally suited for Communications, Military, Industrial and Test Bench applications. The revised range will also form the background to MESL’s range of Space qualified units.

This modular design approach allows a number of different connector types to be used and reduces the delivery to one week for most frequencies. They are also available in circulator versions.
