APPRO
0.4~3.8GHz 3xSPST Antenna Tuning Switch
Description
The MXD8533B is a CMOS silicon-on-insulator (SOI), three
single-pole, single-throw (3xSPST) switch. The high linearity
and ruggedness performance and extremely low R
ON
and C
OFF
makes the device an ideal choice for GSM/WCDMA/LTE
handset antenna tuning application.
The MXD8533B 3xSPST switch is provided in a compact
1.75mm x 1.66mm x 0.37mm package. A functional block
diagram, the pin configuration and package are shown in
Figure 1. Signal pin assignments and functional pin
descriptions are provided in Table 1.
Features
Broadband frequency range: 0.4 to 3.8 GHz
Input 0.1dB Compression Point: 48dBm
RFFE serial control interface
No DC blocking capacitors required
Ultra small package, LGA 11-pin (1.75mm x 1.66mm x
0.37mm), MSL1
Applications
GSM/WCDMA/LTE band and mode switching
