IWR1443BOOST: Why is IWR1443BOOST is outrageously more expensive than IWR1443 itself?

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443,

Hey everyone, I know this is not technical question but I will shoot anyways.

I am interested in mmWave sensors and checked the prices. IWR1443 itself is priced at 30$ but I am illiterate about electronics side, so I can not prepare a circuit to use the chip. I checked the evaluation module for it, IWR1443BOOST and seen that the price is whopping 300$. I bought couple launchpads in my time and they were never that more expensive than the processors on them. What is the justification for this pricing? It just prevents the hobbyists from trying the sensor honestly. And EVM does not even seem that complicated compared to chip itself.

Thanks in advance.

    Hello,
    The implementation of the mmwave sensors requires an RF layout that needs .001 inch tolerance for the antenna dimension, and special RF laminate material for the circuit RF traces. The combination of the TIVA processor, mmwave sensor, QSPI flash, CAN transceiver and Low Voltage power supply are the major elements.

    Under the mmwave sensor BOOST section on the TI website, the schematic, layout, Bill of Materials are posted, and board design are posted if you would like to build your own module.

    There are third party provides for the Automotive and Industrial usage of mmwave technology, D3 Engineering, SRS technologies, are listed on the TI web site.

    If you check the E2E forum there are universities (Idaho State University) that are researching building subsystems, you could contact them.

    I am sorry I can't answer your pricing question, I am an application engineer.

    REgards,

    First paragraph gave me vague idea about why it might be, although if it is no confidential, I would like to learn if only the technical difficulties are the reason for the price. Thanks for suggesting alternatives, I will be checking them surely.
