Broadcom was one I was familiar with... didn't realize they got
purchased. I'm also familiar with Xilinx and Microsemi which they also
got.

Ubiquiti has used mass market WiFi chips in most of their product line
but not typically in the airFiber line which I believe is built around
discrete A/D, processor and FPGA chips. Mimosa is probably the one
that built a licensed radio around a WiFi chipset. More conventional
licensed radios have their own chipsets from companies like MaxLinear.

Check out the Wikipedia article about MaxLinear and their recent
acquisitions, they are quite the powerhouse now.

What Ubiquiti did with the AF11 was use the cheapest chip they could
find that met some other requirements.

Interesting, so I'm guessing that they're able to reduce the noise to
an acceptable level at that high of power by using a narrower
channel... kind of like what Ubiquiti did with the AirFiber 11.

Just an FYI..
According to this chart, the occupied bandwidth is only 64.5 MHz
so you will be losing capacity vs radios that occupy the full 80
MHz bandwidth. The DW radio will have to be coordinated and
licensed in one of the 80 MHz channel allocations as there are no
FCC channel plans between 51 MHz and 79 MHz. There are only
4-channel pairs available at 80 MHz and its difficult to
coordinate multiple pairs in many areas as a result. Finally,
while these power levels are impressive, they don't tell the full
story and you really need to compare the system gain values at the
desired modulations. The DW 64.5 MHz radio’s system gain at 2048
QAM is 83 dB vs. the WTM 4100 80 MHz radio’s system gain at 2048
QAM which will be 73.5 dB.

+31 is the advertised 2048QAM output on the HP variant.
Dragonwave contacted me offline and is indicating a March
availability. Here is the table of power output levels for
that radio. It should also support 4096QAM, but I’m not sure
if that’s available in the software yet.

Looks like PTP820c is only +16.
You’re talking about xmt power actually at 2048QAM modulation,
right? +31 is hard to believe.
I remember hearing that Broadcom was supposed to have a chip
with adaptive digital predistortion for high xmt power also
4096QAM not sure if that became real.

Dragonwave announced over a year ago the Harmony Enhanced
18HP, with +31 TX power at 2048 QAM, but have never made it to
production as far as I know. From the top of my head, here are
some of the major radios TX power in 18 Ghz band:
Dragonwave Harmony Enahcend HP – 31<Vaporware?>
Dragonwave Harmony Enhanced SP – 22
Bridgewave Navigator – 19
Aviat WTM 4200 – 17.5
SIAE AlfoPlus2 – 17
Curious if anyone is aware of an 18Ghz dual core radio capable
of higher TX power at 2048QAM? It’s quite difficult to license
6Ghz or 11Ghz paths in my market.
