The MODEL 805 from Berkeley Nucleonics is a Phase-Coherent Frequency Synthesizer that operates from 100 kHz to 22 GHz. It supports single-channel and multi-channel operations with the ability to link multiple units for phase coherence and multi-channel capabilities in various applications. For multi-channel operation, it supports external references of 100 MHz and 1 GHz with a frequency lock range of ±10 ppm. It also offers a 1 GHz reference output, allowing multiple units to be connected for phase-coherent sources. It can adjust individual channel phases which provides precise timing alignment.
In single-channel mode operation, this synthesizer has a resolution of 10 mHz, a switching time of 5 μs, and a calibrated frequency accuracy of ±30 ppb. It provides an adjustable output power range from -40 to +25 dBm with an accuracy of ±1.5 dB and a resolution of 0.5 dB. The phase can be adjusted from 0 to 360° with a resolution of 0.1° and has a phase noise of -132 dBc/Hz (@20 kHz offset, 1 GHz carrier).
The MODEL 805 is available in a well-shielded, compact flange-mountable module that measures 134 x 95 x 25 mm with a standard Ethernet port for connecting to a PC and controlling the unit with BNC’s graphical interface software or using SCPI commands. It consumes 17 W of power and is available with internal temperature monitoring to prevent the synthesizer from exceeding the recommended operating temperature range.
This frequency synthesizer is suitable for use in various forms and layouts of RF/microwave systems and is a suitable clock for RF/microwave systems, especially when multi-channel and phase-coherent local oscillators are required. It is ideal for designing and testing of radar receivers, phased array beamforming networks, I/Q modulators in quantum computing instrumentation, MIMO receivers, and heterodyne spectroscopic systems. Its phase-coherence and fast switching capabilities also support fast frequency hopping in agile electronic warfare systems.
