Cost Effective Solid State Transmitter Study.

摘要

Cost models were developed based on the performance and physical characteristics of solid state modules. The cost models are sensitive to power,frequency,bandwidth,device characteristics,noise figure,reliability and quantities. However,they are totally independent of specific configuration thus enabling cost estimation of any module configuration,power level,frequency,etc. The models were then used to examine cost sensitivity to frequency,power output and device junction temperatures. This provided guidelines for cost effective design in terms of power levels and operating junction temperatures. Also developed were estimates of 'dollars per watt'for UHF, L and S bands. Comparable solid state and tube transmitters were postulated at the three bands of interest. The study showed that for certain applications solid state systems are competitive with tubes when total life cycle costs are considered.
