| Abstract | Self-oscillating mixers (SOM) are used in phased arrays and other communication systems due to their potential application as both down-converters that do not require an external local oscillator (LO) signal, and phase shifters. Phase shifting properties are introduced to the SOM by injection locking it to an external reference. In this work, the effects of the injection signal power on the performance of an SOM element are investigated. In addition the performance variation along the stable phase shift range is examined. Conversion gain, noise figure and distortion are evaluated. Simulation results are presented using harmonic balance and conversion matrix analyses to trace the various solutions. In addition, the stability of the solutions is verified with envelope transient analysis. The simulation results are compared with measurements on a 3.5 GHz SOM, designed to down-covert an RF signal of 7.1-7.25 GHz to an IF frequency in the range of 100-250 MHz, by mixing it with the $2^{nd}$ harmonic of the SOM. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
