CXG1090EN
High Power 2 ×4 Antenna Switch MMIC with Integrated Control Logic
Description
The CXG1090EN is a high power antenna switch
MMIC. This IC is suited to connect Tx/Rx to one of 4
antennas in cellular handset such as PDC.
The CXG1090EN 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 CXG1090EN to be operated
with low voltage.
Features
• Low insertion loss: 0.30dB (Typ.)@900MHz, 0.40dB (Typ.)@1.5GHz
• Small package: 16-pin VSON
• High power handling: Pl dB: 37dBm
• CMOS compatible input control
• Low bias voltage: VDD = 3.0V
Applications
2 × 4 antenna switch for digital cellular telephones such as PDC handsets
Structure
GaAs J-FET MMIC
Absolute Maximum Ratings
• Bias voltage VDD 7 V @Ta = 25°C
• Control voltage VCTL 5 V @Ta = 25°C
• Operating temperature Topr –35 to +85 °C
• Storage temperature Tstg –65 to +150 °C
Note on Handling
GaAs MMICs are ESD sensitive devices. Special handling precautions are required.
