Microwave Pulse/CW Power Monitors

FEATURES

• 1 nsec Typical Rise Time Response (into 50 ohm load through 50 ohm cable)
• Built-in 1 Watt CW Protection Circuit
• Flat Frequency Response (±0.5 dB typical)
• Matched input for low VSWR (2:1 max for power up to +10 dBm)
• Stable output over temperature range (±0.5 dB typical, -15°C to +85°C)
• Miniature size available
• Hermetically-sealed module for ruggedness

APPLICATIONS

• Direct Measurement of pulse rise time, pulse width and pulse power
• CW power measurements
• Fast feedback leveling circuit
