Help with Part Identification
« on: July 19, 2023, 07:08:06 pm »
Hello All,

Trying to find datasheets for these two parts on a 2.4 GHz hobby radio control link.  One is a switch marked '2244 5430' and another seems to be an LNA marked '5JZ3' or 'SJZ3'.  Google didn't find anything obvious but the pinout seems to align with some SkyWorks parts.  Photos attached.  Many thanks.

Edit:

Switch seems to follow this pinout: SKY13348-374LF
LNA seems to follow this pinout: SKY65971-11

The “2244” part could be a mixer, there is a pi attenuator on the track leading off to the left.
