The operator must insure that the antenna system is properly installed and adjusted. The nature of these protection circuits allow the amplifier to safely trip immediately, sometimes faster than a meter can record a high reflective power or high drain voltage.īecause of the instantaneous response of these circuits couple with the finals low tolerance of high SWR’s, using a solid state amplifier not only requires, but demands that the operator install and maintain an efficient and precise These include protectionĪgainst such issues as, high line voltage, high reflected power, excessive forward power, over current to the finals, over voltage to the finals, internal fuse blown, over driving of the finals, fan inoperative and many other parameters. The finals in solid state amplifiers are not tolerate of high reflectiveĪdditionally, in order to protect the sensitive nature of the MosFet finals and other electronic components, numerous protection circuits have been incorporated in all our amplifiers to limit damage internally. We cannot over emphasize the fact that the operation of a solid state amplifier should not be compared to, even lightly, to the operation of a tube type amplifier. Because our equipment are so technically advanced, some basic concepts should be understood in the operation of a modern, technically superior amplifier. This technology is incorporated starting at the conception phase, proceeds through the design and manufacturing phase and ultimately results in a high performance, highly technical amplifier for use by Amateur Radio operators throughout Manufactured by Tokyo Hy-Power, use the latest technology available. This has impacted all areas of equipment, transceivers, antennas, automatic antenna tuners and of course, amplifiers. With 20 years of experience and extensive use of ATE (Automated Test Equipment), TMS is well placed to support our customers' technical and production needs for all SSPAs.In recent years the technology of equipment available to the Amateur Radio Operator has increased dramatically. These amplifiers utilize state of the art thermal management schemes and unique highly efficient coaxial power combiners to allow designs in smaller form factor with improved reliability. TMS also offers its new Solid State High Power Amplifier (SSHPA) product line providing power from 100W at module level to multi kW at system level, in frequency bands ranging from UHF to Ku-Band. A good example is our 15W Ku-Band SSPA which operates over data-link & Satcom bands with a total weight of less than 0.5 lbs and only 0.5" thick. SWaP (Size Weight and Power) have become increasingly more critical in the design of new and legacy systems. RFM has some of the smallest and lowest weight SSPAs on the market. This enables new design efforts to be completed on time and with reduced risk. GaN is particularly successful in pulsed applications, with many different amplifier designs available up to 18GHz. TMS pulls on existing module designs to support drive chain and control circuits, hence reserving engineering resources to address critical design of power amplifiers with mechanical and thermal integrity. TMS uses LDMOS, GaAs, InP & GaN technologies to meet customer's needs, generally producing custom designs to customer specifications.
