| CXM3540XR [High Linearity DP4T Antenna Switch for GSM/UMTS/CDMA] Preliminary |
>>Description
The CXM3540XR is a high power and high linearity DP4T antenna switch for GSM/UMTS/CDMA applications.
The low insertion loss on transmit means increased talk time as the Tx power amplifier can be operated at a
lower output level.
The Integrated logic decoder reduces component count and simplifies PCB layout by allowing direct connection
of the switch to digital base band control lines with the CMOS logic levels.
Sony GaAs JPHEMT MMIC Process is used.
(Applications: GSM/UMTS GSM/CDMA dual mode handsets, CDMA handsets, UMTS handsets) |
