How voltage and power transfer in cascaded amplifiers work?
[I discuss Noise Voltage versus Noise Figure at end of this answer.]
simply stated

matching will cost you 6dB per interface on the voltage levels

I once lead a team doing RF design on silicon; we concluded there was no need to match over our 500 micron distances on the silicon

I guided the team (all coming from past PCB work, where matching WAS needed), to view the silicon design as broadband opamps where you can use an emitter follower to achieve low Rout, and use diffpairs (bipolar or FET; we have biCMOS process) for input circuit, thus HIGH_RIN,  to the next signal_processing circuit

we learned, in our simulations, the matching made no sense after building a precision gain/phase circuit at substantial power consumption and THEN to throw away 6dB voltage level


===================
At the time of this design team's learning of RFIC methods, a big topic at technical conferences was Noise Figure versus Noise Voltage.
simply put:

Noise Figure requires a given noise density at the signal source

a &quot;noise density&quot; seems to require an Output Resistor

we don't want to insert lossy resistors, just to add noise

so we went with the OpAmp_as_broadband_amplifier for our mindset; we did no matching; we used Noise Voltage as our UHF (300MHz to 3,000MHz) design goal
