The Kalmus 7075LC is a broadband RF power amplifier engineered for industrial test and measurement applications demanding high linearity and low distortion. Operating across 80–1000 MHz, this 75 W unit delivers rated power with exceptional gain flatness and minimal harmonic content, making it ideal for radiated RF immunity testing and similar demanding environments.
## Technical Specifications
• **Rated Power:** 75 W
• **Linear Power (@ 1 dB compression):** 75 W typical
• **Frequency Range:** 80–1000 MHz
• **Gain (typical):** 50 dB
• **Gain Flatness:** ±3.0 dB unleveled; ±1.0 dB leveled
## Key Features
• Wide instantaneous bandwidth supports sweep, pulse, and CW operation without band switching
• Automatic Leveling Control (ALC) maintains output amplitude across the frequency range
• RF gain control for precise power adjustment
• VSWR protection and RF power sensing prevent overdrive conditions and load mismatch damage
• Rugged RF power MOSFET design for field reliability
• Safety interlock input for operator and equipment protection
• Blanking capability for pulse applications
• Rack-mountable form factor with optional bench-top case
• Remote control via GPIB and RS-232 (optional)
• Optional rear connectors for flexible system integration
## Typical Applications
• Radiated RF immunity testing (IEC 61000-4-3)
• Broadband RF power delivery in EMC test systems
• Pulse and CW signal amplification
• Frequency sweep applications requiring low distortion
## Compatibility & Integration
The amplifier integrates into complex test systems with full front-panel control or optional remote command via GPIB and RS-232 interfaces. RF power sensors built into the design prevent load-induced overdrive, protecting both the amplifier and connected loads in high-VSWR environments. Flexible mounting options accommodate standard 19-inch rack installations or portable bench configurations.
