The EV-RADAR-MMIC2 radar board looks attractive for evaluation, but the bandwidth at 250 MHz is rather limited compared to the other radar modules from Texas Instruments. What is attractive about this module is that you can attach external antennas for transmitting and receiving. Are there other modules from Analog Devices that can have external antennas attached which have wider bandwidths? Thank you, Neil
Hi, how much bandwidth do you want to sweep?

The MMIC chipset is only spec'd for 250MHz as you mentioned but it can still operate above an below these limits. There is no artificial limiter or any special test modes required to run the EV-RADAR-MMIC above the 24 - 24.25GHz range in an evaluation setting. Of course then you would need to run your own characterisation at these frequency ranges for production. This will only get you perhaps a few 100MHz extra BW though, so if you were to require any more than this then we wouldn't have much else to offer. The 24GHz chipset we offer is specifically target to the 24GHz ISM band and so there was not much merit in running above these limits for these products.
