When wideband frequency coverage is needed, few signal sources can match the tuning range of the 10-MHz-to-19-GHz Valon 5019 frequency synthesizer from Valon Technology. The synthesized signal generator employs a modular configuration with multiple phase-locked loops (PLLs) to achieve high stability with low phase noise across the near-19-GHz bandwidth. The synthesizer is a good match for many different commercial and military applications, including for test systems, point-to-point communications, and radio astronomy.
“Our synthesizers often replace laboratory generators costing many times more,” said Stuart Rumley, owner and president of Valon Technology. “We listened to our customers’ requests for a low-cost, easy-to-integrate module. The new Valon 5019 frequency synthesizer addresses all these requirements at an extremely competitive price point.”
The frequency synthesizer operates from a voltage source of +5 to +15 V dc using an efficient switching voltage regulator and generates typical output power of +15 dBm across the frequency range. It works with an external reference source, such as a clock oscillator, from 10 to 120 MHz, and can be operated from a variety of control interfaces, including USB, Ethernet, or TTL serial connections.
Phase noise ranges from −130 dBc/Hz offset 10 kHz from a 500-MHz carrier to −99 dBc/Hz at the same offset from a 19-GHz carrier. Tuning resolution is 10 Hz or better, and as fine as 1 Hz for frequencies from about 4.3 GHz and lower.
