Just come back here,as my computer can not connect to gmail server.About
Chinese fake RF power device, you cann't purchase so called "refurbished"
device. Most of them are remark, the seller clean the label and remark any
label what you want, maybe the label is MRF150,but it is remark from a
dead 2SC2879
( ton of this device in market)
I usually purchase these device in USED cndx,they must with soldering tin
even dirty package,or with the PCB together like this
https://item.taobao.com/item.htm?id=531980798010.
they usually are usuable if you are not too unlucky, but very cheap.As
the link , they sold a pcb with 8 MRF150's only $100+, I 'm allmost sure
it can bargain too.
Another tip, the device on Chinese website cheaper than English website.
