ADRF5045 100 MHz to 30 GHz Single-Pole, Four-Throw (SP4T) Switch

ADI’s ADRF5045 is an SP4T switch that operates from 100 MHz to 30 GHz range. This broadband switch requires dual supply voltages, +3.3 V and -3.3 V, and provides complementary metal-oxide semiconductor (CMOS)/low voltage transistor-transistor logic (LVTTL) compatible control.

The ADRF5045-EVALZ is a 4-layer evaluation board. Each copper layer is 0.7 mil (0.5 oz.) and separated by dielectric materials. All RF and DC traces are routed on the top copper layer whereas the inner and bottom layers are grounded planes that provide a solid ground for the RF transmission lines. The top dielectric material is 8 mil Rogers RO4003, offering optimal high-frequency performance. The middle and bottom dielectric materials provide mechanical strength. The overall board thickness is 62 mil, which allows 2.4 mm RF launchers to be connected at the board edges.
