Description
The CXG1064ATN is a high power antenna switch
MMIC. The CXG1064ATN is suited to connect
Tx/Rx to one of 4 antennas in cellular handset such
as PDC.
The CXG1064ATN has the integrated control logic
and can be operated with CMOS input.
This IC is designed using the Sony’s GaAs J-FET
process which enable the CXG1064ATN to be
operated with low voltage.
Features
• Low insertion loss :
0.35 dB (Typ.) @900 MHz, 0.45 dB (Typ.) @1.5 GHz
• Small package : TSSOP-16 pin
• High power handling : P1dB : 37 dBm
• CMOS compatible input control
• Low bias voltage : VDD=3.0 V
Applications
2 × 4 antenna switch for digital cellular telephones
such as PDC handsets.
