Four high performance
units give coverage for the VHF Channels 7-13 and UHF TV Bands 470
- 860 MHz. Optimized for LOW LOSS, these circulators typically
operate at 500 Watts cw, 900 Watts peak power level. |
| |
| |
The units
are designed for efficient heat transfer, however heat sinking must
be adequate to transfer the 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). |
| |
| |
The isolator version has an integral 125 Watt
loaded designed to provide a minimum of 20 dB isolation. |
