DTX-1 Driver Amp

[M0PAI]

Looking for a 23cm amp that will work with low output from dxt-1 @ -5dbm, it would be to drive another higher power amp.

Would be interested in a 70cm too.

Cheers

Have a look at https://amzn.eu/d/0xLK43z It has 15dB gain @ 23cm and according to the datasheet around 22dB @ 70cm

With a screened PCB @ just over £6 it's a no brainer. I use one in GB3EY, which also uses a DTX-1, and two in my Porstdown, one on each of the two SDRs.

With the low output of the DTX-1 being so low it's reasonable to run two of these amps in cascade.

I have used similar devices for 70cms, 23 and for various duties bringing up LOs to suitable levels up to 3.4Ghz. Some actually ARE good to 6GHz but little way of knowing until you test with e.g, Satsagen on a Pluto. Easy enough to replace the supplied device with something of known spec though. There is a wide choice of 3 pin 50R in/Out gain devices.
