Microwave & RF Journal, reverse chronological order:

August 2007: Millimeter-Wave Components Aim for Broad Bandwidths

"Insight Product Co. ( offers a broad line of millimeter-wave and submillimeter-wave components, including amplifiers with as much as 30 W output power at frequencies through 140 GHz, monolithic balanced mixers for applications through 178 GHz, and solid-state and tube-based signal sources through 370 GHz. The firm's recently developed line of Terahertz frequency synthesizers includes frequency coverage from 120 to 180 GHz with more than 30 mW output power and options for frequency modulation (FM) and amplitude modulation (AM)."

March 15, 2007: Frequency Synthesizers Fit Many Modular Formats

"When a frequency synthesizer requirement calls for millimeter-wave signals, few firms can match the lineup offered by Insight Product Co. ( with models spanning 36 to 1250 GHz. The company's 120to-180-GHz source, for example, provides more than 30 mW output power over that range and can be operated locally from the front-panel keypad or remotely under GPIB control. The company features three sources covering 370 to 535 GHz, 526 to 714 GHz, and 667 to 857 GHz with power levels from 4 to 15 mW."

March 17, 2005: Frequency Synthesizers Generate Clean Signals

"For millimeter-wave frequencies, Insight Product Co. ( offers a line of frequency synthesizers in full waveguide bands from 120 to 180 GHz, with output-power levels of 30 mW or more.

Ideal for measurement and astronomy applications, these synthesizers can be equipped with optional AM and FM capabilities and GPIB remote control."

Insight Product Company designed a Insight FS frequency synthesizer for Cornell University's Nobel Prize Laurette Dr. David M. Lee.
