Isolator |
The isolator version has an integral
125 Watt loaded designed to provide a minimum of 20 dB isolation.
* All units are designed for efficient heat transfer, however heat sinking must be adequate to transfer internally dissipated power (from less than 25 Watts in the circulator to about 150 watts for the isolator absorbing rated reverse power.) The forward power rating may be raised by providing adequate heat sinking to keep the circulator body temperature within the rated temperature range of -10°C to + 70°C and will not be damaged by even greater temperature extremes (-30°C to + 90°C).
