Holzworth Instrumentation released a higher output power revision of their popular HSM Series 12.5 and 20 GHz RF synthesizer modules. The phase coherent HSM12001B (10 MHz to 12.5 GHz) and the HSM18001B (10 MHz to 20 GHz) are broadband CW sources which are ideal for use as radar system LOs, system clocks, integrated OEM modules, ATE and embedded systems, as well as benchtop applications.
