Envisioning Multiband Direct Access Microwave SDRs

Today it is possible to design a multiband, direct access microwave transmit path using the latest broadband DAC product from Teledyne e2v semiconductors. This discussion highlights significant benefits of multiband direct access and explores the pros and cons of an experimental prototype relative to a traditional heterodyne design.

In reviewing design options, the webinar moves on to consider frequency planning from DC to Ka-band a range covered by next generation product options. Ultimately a direct access transmitter design is planned for development that appears to promise a 3:1 reduction in frequency control components.
