The deisgn, redisign, build, test, and report phases are complete.

Quadrupler during fabrication and testing

The quadrupler project is complete. The final report was given at the Microwave Update 2023 meeting in Enfield CT in April
Press here for that report which includes information about the design, goals, and achievements of performance.

To summarize, the performance of this device is as follows

These charts show output frequency across X axis in GHz and output power across Y axis in dBm. The cursor is at 47 GHz.
Left is a chart of a typical unit at different input power levels. This unit reached compression at 4 dBm. Chart on right is an overlay of 8 typical units at +5 dBm input.

• Frequency and Signal Levels
• Input 10 GHz to 12.5 GHz
• Output 40 GHz to 50 GHz
• Input Level 3 to 5 dBm nominal, do not exceed 8 dBm input
• Output Level 5 dBm to 12.5 dBm with peak at 47 GHz band
• Power
• 6 to 13 VDC Nominal at 160 mA
• 6 to 8 VDC range if used as a continuous beacon
• Environment
• 25 C or lower Nominal
• 40 C maximum, but only if run at 6 to 8 VDC
• If run as continuous beacon and ambient may reach 40 C, then both
• run at 6 to 8 VCD and
• key source signal rather than keying the quadrupler directly
• Guaranty
• If "Use Instructions" are followed
• Guaranteed for 1 year from purchase date to function correctly (meet specifications)
• I decide whether to repair or replace
• If failure after more than 1 year, or didn't follow "Use Instructions" contact me
