MXD8529 – 0.1-3.0GHz SPDT Antenna Tuning Switch
General Description
The MXD8529 is a CMOS silicon-on-insulator
(SOI), single-pole, double-throw (SPDT) switch.
The high linearity and ruggedness performance
and extremely low insertion loss makes the device
an ideal choice for GSM/WCDMA/LTE handset
antenna tuning application.
The MXD8529 SPDT switch is provided in a
compact 1.385mm x 1.485mm x 0.45mm 8-lead
LGA package. A functional block diagram is shown
in Figure 1. The pin configuration and package are
shown in Figure 2. Signal pin assignments and
functional pin descriptions are provided in Table 1.
Applications
GSM/WCDMA/LTE band and mode switching
Antenna tuning switch
Features
Broadband frequency range: 0.1 to 3.0 GHz
Low insertion 0.30dB @ 2.7 GHz
