I tried to get the datasheet for the BLD6G22L-150BN from RFMW.COM a few weeks ago,
they said its obsolete so they don't have datasheets anymore 
I got the tip from Heiner to ask @RFMW so i think he already did that.

Kurt look here: Low cost (but good) directional coupler
You must have been unlucky and get a defective one.
Such high insertion loss is not normal.

Here are chematics and BIN + HEX file for Arduino Nano (M328P) board

The results against a fresh calibrated R&S signal generator:
2,4GHz
-50dBm > -50,2dBm
-20dBm > -20dBm
-10dBm > -10,3dBm
and on some other bands (not calibrated there!)
1250MHz
-20dBm > -24,4dBm
435MHz
-20dBm > -25,1dBm
145MHz
-20dBm > -25,2dBm

Hi Tom,
on page 477 they write:
" to conduct and complete in time for WRC-23 the sharing and compatibility studies1,
with a view to ensuring the protection of services to which the frequency band is
allocated on a primary basis, without imposing additional regulatory or technical
constraints on those services, and also, as appropriate, on services in adjacent bands,
for the frequency bands:
– 3 600-3 800 MHz and 3 300-3 400 MHz (Region 2);
– 3 300-3 400 MHz (amend footnote in Region 1);
– 7 025-7 125 MHz (globally);
– 6 425-7 025 MHz (Region 1);
– 10 000-10 500 MHz (Region 2)"
Does this mean that only a small part of the QO100 footprint (e.g. Brazil) could be affected?

Then it is useful to provide the information that you already know that link....

One useful function i am still waiting for is the automatic FEC setting from the Signal info.
On every DATV signal you have to manually set the FEC to the value already shown in the Signal info.
Maybe this could be implemented in the next Version?
Tnx

working @ first try
BTW,
abt 36% CPU load (VLC running) on a I5 3470 quadcore CPU

8Psk decode is no problem here. Version 12 in use
2MS beacon is also decoded here with standard rtl_sdr stick set to 2,4MHz bw..
Signals with 5db on the goonhilly can be received good here.
Locking to 125ks is hard and takes a long time but
250ks and up is locking ≤10sec here (if the signal is clean!)

oe3cbs : sure Chris...
here is a eBay link: https://www.ebay.de/itm/RF-Koa…m:mQER6d719NkU5SUiyFRJ_7g
Also have a look at this thread: Low cost (but good) directional coupler

dj0abr : i use a cheap 30dB directional coupler from ebay with a additional 30dB att.
This way i can measure 10mW - 100W with that little meter
If you are interested in the code and the ciruit drop me a PN.
G0MJW : for the ref i use the 3,3V from the USB chip on the nano board.
The detector board has its own 7805 linear regulator.
I use one of the free ADCs to measure the battery voltage and when it drops below
7V (in my case) and the readings change because of low voltage then a "low bat" message is displayed.
-
Now with some more essential functions:
- Selectable external attenuator in 0,1dB steps
- Direct display of mW and W.
- Added two small trimming potentiometers for easy calibration to -50 and -10db
-
Just finished my handheld 2,4GHz powermeter.
Build with a AD8313, Arduino Nano and small 16*2 LCD display.
Works good from -55 to -5dBm with a error <0,2dB from -55 to -5dBm.
Next week i give it to a friend who checks it against a fresh calibrated R&S signal generator.

Ich hatte die Videos mitgespeichert und DM4DS hat sie auf Youtube geladen.
