Sony CXG1101TN Datasheet
Description
The SP3T is a high power antenna switch MMIC for
use in TDMA800/1900/AMPS800 triple mode handsets.
One Antenna can be routed to one of AMPS, PCS Tx
and PCS Rx. This IC is designed using the Sony's
JFET process for low insertion loss.
Features
• Low second harmonics < –31dBm at 29dBm @2.8V
• Low insertion loss: 0.3dB (Ant. – AMPS)
• Small package size: TSSOP-10pin (3.2mm × 2.8mm)
Applications
TDMA800/1900/AMPS800 triple mode handsets.
Structure
GaAs J-FET MMIC
Absolute Maximum Ratings (Ta = 25°C)
• Control voltage | VCTL |5V
VCTL (H) – VCTL (L) 5 V
• Operating temperature Topr –35 to +85 °C
• Storage temperature Tstg –60 to +150 °C
Notes on Handling
GaAs MMICs are ESD sensitive devices. Special handling precautions are required.

When using this IC, the following external parts should be used:
RCTL: This resistor is used to improve ESD performance. 1kΩ is recommended.
CRF: This capacitor is used for RF de-coupling and must be used for all applications. 100pF is recommended.
Cbypass: This capacitor is used for DC line filtering. 100pF is recommended.
