Dave, If you want, I made a layout for the same component footprint as you have. I can upload Eagle "brd" file for it in the file section tomorrow. I think KiCAD can import Eagle. I can also generate

Dave, I eliminated the SMAs. Just put the boards next to each other, bridge with small wires. 73, Gary WB6OGD

Thanks. Looks good overall.

It is actually pretty nice isn't it? Gives me inspiration to make something as nice :-) Ugly style is going to be my first attempt but I have 50 of the filters and a bunch of the inductors and caps

Hi, I hacked the standalone mode by adding another trace showing the combined gain of the LNA and PGA during a sweep.? If the AGC is enabled then the gain can be read in Register 0x69 bits 4-0 The

Footprint QCC8C is the same as Murata footprint SM5050-8, for which I have found libraries (symbol and footprint) and uploaded them in the files section, in the folder VA3NOI. Part number is a

Ah, that makes sense. And I vaguely recall now that you may have stated you were using tape in a previous post. I thought I was seeing the fiber in the exposed fiberglass. Jerry

Correction:? Those are inductors, not caps.

I use Teflon tape to isolate parts of the PCB such as under the sma center line. The PCB is solid copper -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Erik, Your ugly style SAW filter board is actually quite pretty! And if you are getting 70dB of stopband suppression, plenty effective. Could work better than many attempts at an etched board. An

I have made many a custom footprint in ExpressPCB, how hard could it be? You just make a pad, copy it a few times and then group it as a component. I do have Kicad, I do know it is almost impossible

I have a footprint I made myself (KiCAD), but at work at the moment so no access to the PC.? I will put on the files section this evening if I remember. 73 Dave M0WID

I have received a message from Mouser telling me that my request for QCC8C footprint has been discarded due to insufficient information in the data sheet. We are left with the only option of creating

Maybe not as nice but building the filter dead bug style does deliver good performance. The out of band rejection is at least 70dB, Combined with the SI4432 out of band rejection you get about 100dB

Yeah, I didn't search through all his PCB's for the different components he offers... though know he has quite a few.? Not sure if any are QCC8 package... though figured might be worth asking him.

A pretty good suggestion but unfortunately that SAW filter is in a different package (DCC6 versus QCC8).

I made an order yesterday for: https://www.ebay.com/itm/EPCOS-433-92MHz-SAW-B39431-B3740-H110-BW-360KHz-3-0x3-0mm-10pcs/163839895135 Since they already had pre-made PCB's and the size is so small....

Jerry, No, I DO have it working fine, with 5V Nano clone (with level shifters). I do have a custom pin map (to make construction easier and not conflict rx/tx). Erik's code is fine.. except for a
