No they have not suggested any particular antenna. But of course they have mentioned at several places in datasheet.
"input matched to 50 ohm using a high quality‐factor 9.1nH inductor."
My antenna is 50ohm that i am sure about. And this is a general purpose gps lna so ofcourse it is ezpected...
I am trying to match this GPS LNA with a 50hm antenna.
LNA Datasheet:
https://datasheet.lcsc.com/szlcsc/1912111437_AWINIC-Shanghai-Awinic-Tech-AW5005DNRZ_C401025.pdf
Datasheet says that all we need is an inductor around 9.1nH to match it to 50ohm source.But practically when i measure input...
I have to make a simple GPS Receiver board. So i have a Passive Patch->T Matching Network(Values not decided, antenna manufacturer will give me the values once they have my PCB) ->9.2nH(as specified in LNA datasheet) -> LNA -> SAW Filter -> GPSIC
Patch antenna manufacturer has given me a...
I made a device which uses 18650 battery for runing RTC. A coin battery was not possible because the customer did not want the hassle of changing batteries for at least 3-4 years. The 12v is converted to 4.2v (because there are some other things on board which run @4.2v)
I connected the VBAT...
Hi,
In almost all the datasheet of GPS LNA i have read so far, all of them say following
"Output is matched to 50ohm, Input just needs a matching inductor". They even write it highlight this in the features of chip on front page that it just needs one inductor for matching. They also specify...
i need to design two microcontroller based devices, both should have microphone and speaker
and ethernet port.these devices should obtain a fixed ip address say 192.168.1.1 and 192.168.1.2
when connecting through a lan cable, they should be able to act as a simple phone.
I don't know where to...
