The HP/Agilent 83555A is a millimeter-wave source module that generates RF signals across the 33 GHz to 50 GHz band. Driven by compatible Keysight microwave sources, it extends baseband synthesizers into the millimeter-wave spectrum for waveguide-based testing. The module delivers leveled output power with tight accuracy and low spurious content, supporting external pulse, AM, and FM modulation for dynamic signal characterization.
## Technical Specifications
• Frequency Range: 33 GHz to 50 GHz

## Key Features
• Modulation support for external pulse, AM, and FM modes
• Leveled output power for stable signal generation
• Low harmonic and non-harmonic spurious content
• Compact waveguide-flange output (WR-28)
• Frequency multiplication architecture — extends driving source capabilities into Ka-band
## Typical Applications
• Wireless communication system testing
• Radar system characterization
• Millimeter-wave component evaluation
• Waveguide-based signal generation
## Compatibility & Integration
The 83555A integrates with HP 8350B series sweep oscillators and the HP 8350A RF plug-in for swept-frequency measurements. System frequency coverage scales directly with the driving microwave source; sources operating 11 GHz to 20 GHz with output power exceeding +17 dBm enable coverage to 110 GHz across waveguide bands when paired with modules like the HP 83623B, 83624B, or HP 8349B amplifier. Compatible with HP 8510 vector network analyzers, HP 8757A scalar network analyzers, HP 5343A frequency counters, and HP 8970 noise figure meters.
