Exploiting more than 70 years of design and development experience in frequency control and timing, Valpey Fisher has leveraged its knowledge base to launch a new technology platform: integrated subsystems. It was introduced at last week’s IEEE Microwave Technology and Techniques Symposium in Long Beach, Calif.

Rather than simply supply a discrete component, Valpey Fisher’s integrated subsystem approach offers the design engineer a complete solution. The basic building block of every integrated subsystem features a very high-frequency, very low phase noise reference oscillator. The subsystem is then designed with additional components to provide multifunctionality based on the customers' unique requirements. By integrating multiple components on the block diagram into one complete subsystem, reliability will increase and cost will go down, said the developer.

The first product launched off of the integrated subsystem technology platform is a high-frequency reference module that provides +20 dBm of RF output power and operates with extremely low phase noise (-90 dBc/Hz at 10Hz offset from the carrier, -170 dBc/Hz on the noise floor at 100 MHz) and meets stabilities as low as 0.1 ppm. Consisting of a high-precision OCXO, power amplifier and an output filter/matching network, the entire subsystem fits neatly into a 2-inch x 2-inch x 0.75-inch package.
