The switch provides high linearity performance, low insertion loss and high isolation.  Simultaneous voice and LTE systems  Diversity antenna switching Switching is controlled by one control voltage,V1. Depending on the logic voltage level applied to this pin, the RF1 and RF2 pins connect to one of the two other RF port pins (RF3 or RF4) through a low insertion loss path, while maintaining a high isolation path to the alternate port. No external DC blocking capacitors are required on the RF path as long as no DC voltage is applied externally.  Single control voltage input  Broadband frequency range: 0.4 to 3.8 GHz  Low insertion loss: 0.55 dB @ 2.7 GHz  P0.1dB of 37dBm  No DC blocking capacitors required  Positive control voltage range: 1.8 to 3.3 V The MXD8546 DPDT switch is provided in a compact Quad Flat No-Lead (QFN) 1.83 x 1.83 mm package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2.
