Look for a logo or other identifying mark on the device.
I was able to find a DBM made by Hittite, HMC412MS8G . It's a small 8 pin IC
in the MSOP8G SMT package.-Mike-WA6ZTY

I am trying to locate some info on the transmit double balanced mixer used in
this radio. The schematic calls it a 412E-H. It is built on a circuit board
with 2 toroids and a diode pack cover with plastic. I do not know the
manufacturer. Any help? Thanks Mike
