NOMINAL IMPEDANCE: 50 Ω FREQUENCY RANGE: dB VALUE Units are screened 100% as follows: Deviation (dB) + 0.5 / -0.0 + 0.50 + 1.00 + 2.00 MAXIMUM SWR: Frequency (GHz) SWR dc - 32 1.25 Thermal Shock: 10 cycles, -55°C to +100°C Peak Power: 500 Watts, 5 μsec pulse width; 0.05% duty cycle for 3 minutes at each end. DC Attenuation is measured before and after peak power. Monitored Thermal Cycle: Units are subjected to 10 thermal cycles between -55 °C to +100 °C. The PIN-to-PIN DC resistance is continuously monitored and stored. Attenuation and SWR are tested as final electrical test. MODEL NUMBER DESCRIPTION: POWER RATING: 2 watts average to 25°C ambient temperature, derated linearly to 0.5 watts at 100°C. 500 watts peak (5 μsec pulse width; 0.2% duty cycle). Example: 32J - XX POWER COEFFICIENT: < 0.005 dB/dB/watts TEMPERATURE COEFFICIENT: < 0.0004 dB/dB/°C TEMPERATURE RANGE: -55°C to +100°C CONNECTORS: SMK (2.92mm) connectors - mate nondestructively with SMA, 3.5mm and SMK (2.92mm) connectors.
