Power Handling (Watts)
Notes:
1. Plot refers to incident continuous power of “P” Watts
2. Mounting surface is assumed an isotherm at T
M
°C
3. Actual testing done at P = 100 Watts, T
M
= 100 °C
4. Plot based on 1-dimensional heat transfer formula: T = T
M
+ PR, where
T = area-average resistive film temperature, held to 150 °C, max.
R = thermal resistance, mounting surface to resistive film ≈ 0.5 °C/W
for 30- and 20- dB devices (other values will run cooler and therefore
handle more power – consult factory)

Mounting Surface Temperature (°C)
* Test Condition: With mounting surface temperature = 75°C, max. (see plot above). Actual test conditions are as follows: Flange attached to a large
copper carrier whose surface, directly under the flange center, is held at 100°C; power applied = 100 Watts. Specification: The attenuation shall change
no more that 0.2 dB during and after a 100-hr. Burn-in per MIL-PRF-55342.
** Attenuation vs. frequency as a function of temperature, -55°C to +125°C
