Customised devices available
For more 50 W-CW input power, cooling is necessary by conduction via heat sink (RTH = 0.4°C / W max.)
1) High power device
2) Specifications are absolute maximum ratings at high power (listed Avg. power)               
3) With SMA, N connectors or tab integrations depending on max. power level request
4) 200 W-CW on 3: 1 continuous load VSWR. Permanent short circuit duration: 3 sec. max.
    100 W-CW on permanent short circuit handling, cooling by conduction via a heat sink
    (RTH = 0.4°C/W max.)
5) 10 % bandwidth

For more than 50 W-CW input power, cooling is necessary by conduction via heat sink (RTH= 0.4°C/W max.)
