FUNCTIONAL DESCRIPTION
Amplifier
The CGY2032TS is a 3-stage GaAs power amplifier
capableofdelivering500 mW(typ.)at1.9 GHzintoa 50 Ω
load. Each amplifier stage has an open-drain
configuration. The drains have to be loaded externally by
adequate reactive circuits which must also provide a DC
path to the supply.
The amplifier can be switched off by means of a single
external PNP or PMOS series switch connected between
This switch can also be used to vary the actual supply
voltage applied to the amplifier and hence, control the
output power.
This device is specifically designed to work with a duty
factor of 50% and can work up to 100% with good thermal
performance printed-circuit boards.
Biasing
Internal biasing is provided inside the amplifier for
class AB operation.
