I don't think that this will "shake up" the amateur world, but it certainly looks like a very worthwhile contribution and it does appear to have a number of uses besides just communication. So I will be quite interested to see what all develops. If it can indeed be made to function as the core of a spectrum analyser then it would have immediate value to quite a few people, both hams and experimentors. BUT please don't compare them to Ardunio. Those ardunio projects always substitute a microcontroller board for a function that could be done with a simple comparator. A shameless promotion of a product line at the expense of understanding actual circuitry.

There is not any baseband modem on the board but ADC and DAC (features of LMS6002D). As Peter said above BladeRF includes all stuff (FPGA + ARM9) to play with mentioned standards. I like it.

Definitely going to shake up the amateur radio world.

"Myriad-RF boards use FPRF transceivers to support all the mobile broadband standards – LTE, HSPA+, CDMA, 2G..." Does this mean that the board can send and receive according, to, e.g. the CDMA PHY standard? Or does it mean that the board can send and receive at the relevant rf frequencies and actually imposing the digital signal on top of that is up to you?

It is interesting to note that the BladeRF is based on the LMS6002D IC from Lime Microsystems because as Nuand states: "this transceiver is capable of handling anything from simple FM audio to the latest 4G LTE standard." BladeRF does include the FPGA and a USB 3.0 digital connection and bus power.

Take a look at the BladeRF from Nuand: www.kickstarter.com/projects/1085541682/bladerf-usb-30-software-defined-radio They have an open source radio platform which uses GNU Radio and provides analysis. I have been rather rash and ordered one already!

Maybe this would be useful to teach RF at schools?

If they added a signal analyzer software bundle, I would be very interested. I can see a lot of uses for a device like this one. Just my opinion,

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
