RF Switch required for Iridium Satellite Transceiver

Hi, I need to switch an Iridium satellite transceiver between two identical passive antennas. The Iridium transceiver has the following specifications:


Operating Frequency: 1616 to 1626.5 MHz

Average Power during Transmission (Max): 38.45 dBm

Peak transient Power during Transmission (Max): 40 dBm

Transceiver Receive Sensitivity at 50Ohm: –118 dBm

Impedance: 50 ohm


So I am looking at a reflective SPDT switch, something similar to the ADG919 that can handle the power input (40 dBm) and ideally powered from a standard 5 or 3.3 VDC supply. I also prefer that the deselected port is shunted to ground although open circuit is ok….any thoughts please ?
