"RDA-6A / RDA-8A Reference Distribution Amplifiers"

April 28, 2009 - JWM Engineering Group announces the RDA-6A and RDA-8A Reference Distribution Amplifiers. Developed to provide laboratory grade performance, the RDA-6A provides (6) independently isolated outputs that can be used to drive the external 10 MHz reference inputs of test equipment. The RDA-8A provides (6) outputs for 10MHz use and (2) additional 5MHz outputs for test equipment that require a 5MHz reference, like HP-8640 Signal Generators. Now you can use your PRS 10 Rubidium reference or GPS Disciplined oscillators like the Trimble Thunderbolt, or a highly stable OCXO to synchronize all your frequency counters, spectrum analyzers, and signal generators to one reference standard. The isolated outputs prevent interaction between all your test equipment reference inputs, assuring accurate measurement data.

"Upgrade to Low Noise Phase Locked Performance"

June 20, 2008 - JWM Engineering Group announces its latest Microwave Low Noise Phase Locked products. These units were developed to replace the older Model 1152 and Model 5112 PLL and provide an increase in performance along with an improved industrial package.

  • The Model 1152-A provides a direct replacement to the DEMI MicroLO product or it can also be used as a Microwave Beacon driver at 1296 MHz.

  • The Model 1152-ALN is a single frequency ultra low noise PLL designed for extreme low noise operations like digital communications, long-haul communications and EME operations at 1296 MHz. This unit provides the LO frequency of 1152MHz for a 144MHz IF frequency.
  • The Model 2160-ALN is a single frequency ultra low noise PLL design for extreme low noise communications like digital communications, long-haul communications and EME operations at 2304 MHz. This unit provides the LO frequency of 2160MHz for a 144MHz IF frequency.

  • The Model 2556-ALN is a single frequency ultra low noise PLL design for extreme low noise communications like digital communications, long-haul communications and EME operations at 10 GHz. This unit is a direct replacement for the DB6NT Transverter LO chain and uses the last times (4) multiplier in the transverter.
  • The Model 2808-ALN is a single frequency ultra low noise PLL design for extreme low noise communications like digital communications, long-haul communications and EME operations at 5760MHz. This unit provides the LO frequency of 5616MHz for a 144MHz IF frequency, when multiplied by an external times (2) multiplier.

  • Custom frequency units are also available.
