Macro X is a 4 lead component package the is used for RF transistors1. As of 2022, the package seems obsolete.
Microsemi’s BJT pinout for this package connected the longest lead to the collector, the lead opposite this to the base, and the other two leads to the emitter1.
Macro X package is similar to Macom’s
CASE 305A-01 component package, used for the Macom MRF158 N-channel RF MOSFET3.
