14 pin UQFN (Plastic)
SP4T Antenna Switch for GSM
Description
The CXG1194UR is a high power SP4T antenna
switch for GSM applications. The low insertion loss on
transmit means increased talk time as the Tx power
amplifier can be operated at a lower output level. On-
chip logic reduces component count and simplifies the
PCB layout by allowing direct connection of the switch
to digital baseband control lines with the CMOS logic
levels. This switch is SP4T, one antenna can be
routed to either of the 2Tx or 2Rx ports. It requires 2
CMOS control lines. The Sony GaAs JPHEMT MMIC
process is used for low insertion loss.

Electrical Characteristics are measured with all the RF ports terminated in 50
.
Harmonics measured with Tx inputs harmonically matched. It is recommended that the harmonic matching is
used to ensure optimum performance.
