SPDT Switch for 3G/4G Applications
Description
The MXD8626C is a Single-Pole, Double-Throw (SPDT)
LTE/WCDMA switch. Switching is controlled by a GPIO
interface with a single control pin.
The MXD8626C is provided in a compact 1.1mm x 0.7mm x
0.45mm 6-lead DFN package, which meets the requirements
for board-level assembly. No external DC blocking capacitors
are required as long as no DC voltage is applied on any RF
path. A functional block diagram and the pin configuration are
shown in Figure 1.
Features
Broadband frequency range: 0.4 to 3.0GHz
Low insertion loss: 0.35dB @2.7GHz
High isolation: 25dB @2.7GHz
High Input 0.1dB compression point: 35dBm
Single GPIO control line with VDD voltage regulator:
