This low-profile multiplexer has a passband of 500 MHz to 2 GHz with an insertion loss of 2 dB, a typical VSWR of 2.2:1, rejection of 40 dB, and an operating temperature of -55°C to +55°C. It measures 2.5 x 1.75 x 0.375 in. and uses female SMA connectors. Sets are available with a maximum of six units phase-matched to +/-15 deg. across the passband. They are designed for use in hostile operating environments and are housed in a 6061 aluminum enclosure that is laser welded to meet hermeticity specifications. The multiplexer meets various environmental specifications within MIL-STD-202, which makes it an excellent means of allowing multiple RF signals to enter a controlled switch that selects which input is allowed to pass through to the desired output.
