Single-Chip Transceiver

[NZ0I]

This thread is off topic, but related to the task at hand. The following EZR32WG230 product is a transceiver-on-a-chip that appears to cover all of the VHF and UHF Amateur Radio frequencies between 144 MHz and 1 GHz:

That device would be a totally separate project unto itself.

At first I disregarded it since it is clearly aimed at short-range digital-communications applications. But upon closer inspection, it is very configurable, and includes DAC outputs that can be used for audio output. I haven't looked into this device enough to determine if it is truly suitable for CW ARDF use, but so far I can't rule it out.

Since it is a transceiver, it could potentially be used for "foxes", receivers, or for remote control of foxes on a separate UHF band.

Developing a "EZRadioPRO sub-GHz RF transceiver" for 2m would probably involve starting with a "Wireless Starter Kit Mainboard" for 169MHz and using it as a baseline for designing a DIY Wireless Starter Kit Mainboard for 146MHz. Then one could probably use the development software provided by Silicon Labs to do the development work.

So much of the radio is integrated into the chip that it should (with a good deal of work) result in inexpensive radio devices.

I could see this used in controls to send packet data back when the control is punched. 

Or used as a remote control on uhf for vhf or hf transmitters.

That's just one of many ham applications that could be made with a chip like this. A good find.
