Description
The SP4T + logic is a high power antenna switch MMIC for use in dualband GSM handsets.
One Antenna can be routed to either of the 2 Tx or 2 Rx ports. It operates from 3 CMOS control lines (Tx ON/OFF and GSM900/1800 and Standby).
The Sony's J-FET process is used for low insertion loss.

FEATUREs
• 3 CMOS compatible control lines
• 34dBm power handling at 5.0V (GSM900)
• Low second harmonic < – 30dBm at 34dBm
• Small package size: 16-pin TSSOP (3.9 × 4.1mm)

APPLICATIONs
  Dualband handsets using combinations of GSM900/GSM1800/GSM1900 and DECT
