are there power levels where they stil use wavegides and the like?


As much to do with frequency as power level. I've recently completed
the design of a Ka band transceiver for satellite (30GHz uplink, 20GHz
down). It is a domestic product for delivery of broadband to rural
areas. All of the internal RF filtering is done in waveguide, as is
the external combining of the transmit and receive signals into a
single horn. The transmitter power is just 3W.
