High power isolators
High power isolators
Hi,
as some of you may know I'm organising a group buy of some drop in isolators rated at 200 watt forward and 100watt reflected with a 30dB 100 watt attenuator on the 3rd port. Centred on 2400MHz.
Base unit price is $18 but there are fairly big overhead charges which push the end price up to about £28 each plus P&P Maybe less depending on admin charges and exchange rates
We're currently at the 10 unit price break increasing the order to 15 units would bring the price down to £23.60 each.
If you're interested please let me know asap as I'll be placing an order this weekend.
Regards Tim

Re: High power isolators
got it, you're on the list for two and have helped bring the cost down for everyone - thanks
FYI problem is DHL shipping costs at circa $90 plus VAT on goods and various admin fees. Spreading the cost of these overheads really helps everyone.

Re: High power isolators
DHL seems very dear?
Re: High power isolators
Yes DHL is expensive they quote between $81 and $87 for 1 to 25 units,and there maybe admin charges on top of that at this end, so I'm being cautious in my calculations when figuring the estimated unit cost.
I will be asking if they offer other means of shipping and will pass the savings on if it works ok.
On the plus side for DHL at least we can be sure they will get here in a timely manner and not get lost plus when the cost is spread out across all units / purchasers it becomes more reasonable.
I might order a few extra units at my expense for any 'stragglers' - again this will get the unit cost down for everyone.

Re: High power isolators
Pardon my ignorance but when you say "drop in", I assume you are talking about solder on to PCB's and not connector'ised? Just starting and trying to consider what my options on TX are.

Re: High power isolators
This raises the question on how to use drop in isolators. Any ideas for PCB? See here https://john1ghg.home.xs4all.nl/13%20cm ... -47L-1.jpg

Re: High power isolators
Yes drop in are screwed directly to the underlying heatsink and have small tabs which solder to the adjoning PCB trace (s),
Just as in your photo.
I plan on mounting mine directly to the PA output pcb trace with the output N type connector directly above the isolator output tab - so no PCB required.
Any slight mismatch caused by the transition from isolator tab to N type pin will be dealt with by the isolator.

Re: High power isolators
Stick me down for one, please let me know what you require. I will treat it as an insurance for when i get going.
