OK for SMA but a bit high for For 3.5mm, 2.92mm, and 1.85mm as the recommended torque is 8 in-lbs Perhaps HUBER+SUHNER? should standardise there 8 mm Torque wrench to below 1 Nm at 8 in lbs making it compliant ?with ??? ???

Has there been an update on this? Did I miss a post (again) mentioning where the file(s) have been posted? How's the scanning going? Is there any evaluation of the type and range of information in that 1.5 inch thick stack? Asking because I'm currently going through a recent acquisition of HP spare parts, most with only the HP part number identifiers. The more of them I can identify as standard parts and merge with my main, pretty compact, parts stock the better. But my set of HP part number cross-refs is quite limited. |

Hi George, all, thank you! I resumed this thread and found the Geroge's tips. Thank you very much @George. I started to check the two diode that I am able to identify on the left of T301 (CR301 and CR306) and both seem OK. CR301 is also directly connected to a transistor Q301 that I am not able to identify (1AM or IAM ??).
Could you so kind to explain how I can use a 9V pp3 battery to check this board? Do you mean inserted with the other two boards in the assy or I can test it alone on my desk and a simple 9V battery? |

Re: Mating APC 3.5 with APC 2.92 connectors
开云体育Hi Steve it has been a long time since we have spoken ? Regarding maximum torque I recently read about the torque requirements but unfortunately I cannot find the article? it defined the Torque settings for SMA , 3.5 , 2.92,alao 2.4 , 1.85 and they were not all the same? ? Do you or anyone have the Torque settings for the above connectors ? From: [email protected] [mailto:[email protected]] On Behalf Of Steve - Home

Re: Mating APC 3.5 with APC 2.92 connectors
Hi Paul!?
Yes, Mini Circuit Labs (MCL) is very much different firm from when Harvey Kaylie left AIL and started making DBM's on his kitchen table in the Bronx (he used relay cans because they were cheap, soldered so hermetic, and people recognized them). The evolution of their company is incredible.
I was invited to bring some Ham MW equipment to the IMS in Baltimore in 2011 or so. I displayed the stuff and also got to walk around the place and look at the exhibits. At a time when a booth for the week was like 10x20 feet and cost in the thousands for the week (15-20 K for a booth??), MCL had, like, 30 booths worth of space and were showing off 18 GHz Test Cables, Signal Generators up to 18 or 26 GHz all sorts of MW products, higher than 2 GHz. They must of had 50 people working the spaces. This was 12 years back. They have changed and are probably the single largest supply of microwave parts going as far as single source and variety.

I doubt most MiniCircuits SMA connectors are only rated to 2 GHz...

Re: Mating APC 3.5 with APC 2.92 connectors
Hi Dave,
many thanks for the paper also from me, very informative! Hi Martin, unless you do some very critical work and need to see 50dB of matching... :)I think, this isn't even possible with commercial grade equipment. When I worked with the PNA-X and the Rosenberger 67GHz 2,92mm cal kit, I have noticed that the fixed load is assumed as ideal over the full frequency range. The actual load would have to have a better match than 50dB to measure 50dB match. I don't think it has. 40dB match is already very challenging. Also, opening and closing the connector yields effects of this order. Moreover, I have noticed that neither the open nor the short standard is modelled with any loss. Maybe, I'm too spoiled with low frequency measurement accuracies... Best regards, Tom DG8SAQ |
