SKY13575-639LF Block Diagram Description The SKY13575-639LF is a dual-band single-pole, four-throw switch with an integrated 50  match on all RF output ports. External DC blocking capacitors are required on the RF paths. The switch can operate over the temperature range of 40C to 90 C. Switching is controlled by two CMOS/TTL compatible control voltage inputs: VC1 and VC2. Depending upon the logic voltage level applied to the control pins, the RFC pin is connected to one of four switched RF outputs (RF1 to RF4) by a low insertion loss path, while the path between the RFC pin and the other RF pins is in isolation. The isolated ports are terminated to a 50  load. The SKY13575-639LF is ...
