Looks as though MCL is doing jazz trying to line up a second source for the ex-Avago parts. I'm lobbying my rep for ATF55143 and 38143 workalikes, so any other pHEMT phans might want to do the same.
Hopefully Skyworks keeps making the SKY65050, which has much better dc specs but is a bit noisier--400 pV/sqrt(Hz) flatband noise vs. 300--and has a 1/f corner of ~30 MHz vs 10.

I like the SOT89, the ATF-50189. It switches an amp in picoseconds, and makes a 1 amp, 1 pF diode. I'll miss it.
Well, bug your MCL guy about it. Mine was surprisingly receptive to the idea of their selling pHEMTs as well as amps.

Don't CEO's pay attention to letters from other CEO's? Write them.
