The CGY2010G and CGY2011G are GSM class 4 GaAs
Monolithic Microwave Integrated Circuits (MMICs) power
amplifiers specifically designed to operate at 4.8 V battery
supply. These ICs also include a power sensor driver so
that no directional coupler is required in the power control
loop.
Both ICs have the same performance but are issued from
different wafer fabs.
The PAs require only a 30 dB harmonic low-pass filter to
comply with the GSM transmit spurious specification.
They can be switched off and their power controlled by
monitoring the actual drain voltage applied to the amplifier
stages.
APPLICATIONS
•880 to 915 MHz hand-held transceivers for E-GSM
applications
•900 MHz TDMA systems.
