Small-Size Complex Microwave Devices (CMD) for Onboard Applications

Small-size complex microwave devices (CMD) are designed for applications in onboard air-, sea-, and ground-based radio-electronic systems. They are compact integrated multifunctional devices, which are capable of providing generation, processing, and amplification of complex multifrequency microwave signals, although their operating frequency band is relatively low - about 2%. Small-sized and miniature multiple-beam klystrons are, as a rule, the output power tube of choice for onboard CMDs. CMDs are usually applied to systems where high power, high level of integration (multifunctionality), and high signal quality are desired. Design parameters and performance capability for several onboard CMDs are discussed in this paper. In addition, distinctions between onboard CMDs and state-of-the-art onboard microwave power modules are considered
