For conditions, see Chapters "AC characteristics" and "DC characteristics". ORDERING INFORMATION TYPE NUMBER CGY2013G PACKAGE NAME LQFP48 DESCRIPTION plastic low profile quad flat package; 48 leads; body mm PARAMETER (1) positive supply voltage positive peak supply current maximum output power operating ambient temperature MIN. TYP. GENERAL DESCRIPTION
The is a GSM class 4 GaAs Monolithic Microwave Integrated Circuit (MMIC) power amplifier specifically designed to operate 3.6 V battery supply. The PA requires only 30 dB harmonic low-pass filter to comply with the GSM transmit spurious specification. It can be switched off and its power controlled by monitoring the actual drain voltage applied to the amplifier stages.
