We designed and built for production a 4 channel Quad Converter. Our Quad Converter design features:

• 2 Input IF's from 2.2-5.3 GHz, available simultaneously
• Output IF's: 4 outputs at 750 MHz, 375 MHz wide, providing 1.5 GHz instantaneous bandwidth across the input IF's
• Control and Status: VME Interface A24 D32 and UART Serial Interface
• Designed to drive 4 1 GHz Digitizers linearly up to +12dBm
• 5 custom surface mount RF assemblies mounted to an aluminum plate
• Separate multilayer circuit board accommodates power conditioning, FPGA signals and VME interfacing
• Form Factor: VME 6U 1 Slot Design
• RF Connector Interface: SMA

This is a very complex design with very high density surface mount assemblies. Surface mount assemblies are built using pick and place machines at a contract manufacturer. Automated RF test rack, fixtures and software has been designed at R. A. Wood Associates.
