amps in cell towers

[LaserTazerPhaser]

What RF transistors do they employ in those pole or other shaped cell tower radio transmitters? Maybe someone here can post whats inside, they likely have very useful power parts.

LDMOS n-type transistors are fairly common in power amplifier design. Typically these are done on a silicon process, but you can get ones made on GaAs and GaN (or your preferred flavor).

You may sometimes even find that there are two N-type devices in the single package. This is convenient as it allows for Doherty, balanced or push-pull configurations.

I know Gallium Nitride (GaN) is seeing increasing use in DC-DC converters due to their lower loss and higher breakdown voltages (they are also direct bandgap compared to indirect for silicon). However, they are a pain to control as they are depletion mode devices.
