Rakon releases low phase noise, space-grade VCO

Rakon 21 January 2021

Rakon has launched the RVC1616S – a space qualified, hybrid Voltage Controlled Oscillator (VCO). Based on proprietary thick film technology, the design uses low noise bipolar transistors and hyber abrupt varactor diodes. The technology advances phase noise performance and provides high reliability and improved thermal management.

The RVC1616S is 100 kRad (Si) radiation-hardened and hermetically sealed, to operate in the harsh environment of space. It is a 16-pin flat pack device in a 16 x 16 x 4.3 mm package size and is available with the option of straight or gull-winged formed leads. Its thick-film optimises the RVC1616S’s Size, Weight and Power (SWaP). Output frequencies are available from 900 MHz to 1.5 GHz.

Key Features

  • Based on thick-film technology using bipolar transistors and hyberabrupt silicon varactor diodes
  • Excellent phase noise and an extended tuning voltage range available
  • Phase noise @100 kHz offset -122 dBc/Hz
  • Fixed frequency, narrow, and broadband solutions are available
  • Broad band frequency tuning range
  • Hermetically sealed packaging
  • High reliability and qualified to ISRO-PAS-206 standard


  • Space applications where low noise and fast tuning is required such as frequency synthesisers and digitally tuned oscillators

The RVC1616S offers satellite and space craft designers exceptional performance for geosynchronous orbit (GEO) and other deep space applications where radiation-hardened specifications are critical. With a broad product portfolio and comprehensive clocking domain expertise, Rakon can quickly customise, simulate and manufacture complex hybrid VCOs to operate within the most extreme environments.
