New radio technology is hastening the development of impulse radios such as MIR, Smart radios, Software Defined Radios (SDR) and Cognitive radios. Research in radio has an impact on wireless communications, and new spectral friendly radios must be low cost, low power consumption, and conform to Ultra Wideband (UWB) radio regulations. Proposed MIR radio is flexible and adaptable to UWB for implementation in low cost chip format using integrated circuits. MIR research is separated in  phase I and phase II with common aim to acquire needed knowledge for industrial prototype. Commercial components are assembled , in phase I, alongside a digital signal processor to test new multi (six-port) circuits and MIR radio software. In phase II, MIR is  fabricated with in-house integrated circuits (MHMICs) to obtain needed knowledge to design and fabricate an industrial MIR radio prototype. MIR radio will provide short range /high data rates communications found in consumer/ commercial / military multi-user markets.  MIR hardware and software are based on 1995 paper by applicant published in IEEE as "Computer and Measurement Simulation of a New Digital Receiver Operating Directly at Mm-Wave Frequencies". This first paper on direct digital six- port receiver won for applicant the 2004 McNaughton Medal, IEEE Canada's highest award. A similar six-port receiver publication was made, five years later, by an international core research laboratory (Sony). Nevertheless,the six-port demodulation concept of applicant remains in public domain due to priority 1995 IEEE paper. Present MIR project adds new important elements to 1995 publication: 1) a new wideband multi (six) port modulator circuit, 2) a new wide band digital modulation scheme and 3) operating software. Knowledge from MIR research will lead to low cost radio chips and software operated in a laptop or personal computers. This new knowledge will add to Canadian experience in UWB radio. MIR is expected to surpass other UWB radios in cost, power consumption and size to perform basic wireless radio functions (e.g. between computers in office or home) over short distances at high data rates. Similar MIR technology applies to radar (cars, helicopters , aircraft landing and item tagging).
