Conversion Gain Measurement of an LMDS Transmitter

Microwave transmitters are essential elements in future LMDS systems. Conversion gain of an LMDS transmitter is an important parameter which establishes basic functionality and system performance. This paper presents a real-time conversion gain measurement technique utilizing swept scalar analysis and compares the results with a traditional discrete point method. The new scalar technique overcomes measurement obstacles such as an inaccessible local oscillator and a non-insertable DUT.
