Greenray Industries is a leading designer and manufacturer of high-performance quartz crystal oscillators for the military and defence industries.
Greenray Industries is a renowned manufacturer of oven controlled quartz crystal oscillators (OCXOs) temperature compensated quartz crystal oscillators (TCXOs) and voltage-controlled quartz crystal oscillators (VCXOs). Precision quartz crystal oscillators operate as accurate signal sources for military, communications and instrumentation applications.
Greenray is dedicated to supplying tight stability oscillators over wide operating temperature ranges to satisfy the special needs of our customers. Low-phase noise along with very low G-sensitivity is also a priority, and these components come in a range of package options, including Summit (SMT).
While offering outstanding vibration, shock and acceleration sensitivity performance, our ruggedised components also provide competitive stability and phase noise characteristics.
The stability performance of some of our TCXOs matches that of an OCXO, but without the excessive power draw and warm-up period. We also supply self-calibrating oscillators with excellent reliability and long-term stability.
For the military market, we provide products for smart munitions, missile guidance, mobile receivers and radar systems.
Our high-performance frequency control devices are designed for demanding applications from 1Hz to 1GHz. All design, testing and assembly is performed at our facility in Mechanicsburg, Pennsylvania, US.
Greenray provides the communications industry with specially designed products, including Stratum III and IIIE along with wireless and SATCOM.
In addition, we provide components for global navigation satellite systems. Many of our low-noise / tight-stability oscillators are also used for instrumentation applications.
Greenray Industries’ latest product releases include the leading, high-performance T1241 and T1243 TCXOs.
The T1241 and T1243 TCXOs feature very low G-sensitivity, down to <5×10-11/g and are available from 10MHz to 50MHz (T1243) and 50MHz to 100 MHz (T1241) with CMOS output.
Featuring ruggedised, SMT packages and low current draw, the T1241 and T1243 TCXOs are ideal for mobile applications requiring superior phase noise performance under shock and vibration.
The new, high-performance YH1485 oven-controlled oscillator features low phase noise down to 180dBc/Hz and is available from 10MHZ to 120MHz with 10dBm sinewave output.
In addition, the YH1485 comes with low acceleration sensitivity down to -3G to 10/-10G for better performance during shock and vibration.
The YH1485 is assembled in a 1in square, compact, low profile package and uses 15VDC or 12VDC supply. Electronic frequency control (EFC) is offered for phase locking or precise tuning applications.
The above products rank highest for G-sensitivity and phase noise performance.
Greenray celebrates our 55th anniversary in 2016, encompassing a productive, enduring relationship with the military and defence community.
Greenray utilises the unique expertise of each of our two sister companies to enhance our capabilities, and to help us produce several frequency control components with the highest performance available.
