Product Overview
ADRF5019BCPZN is a nonreflective 50 Ω SPDT RF switch covering 100 MHz to 13 GHz. It is intended for signal routing where the unused port should remain internally terminated rather than becoming a high-reflection open path.
At 8 GHz, the device combines approximately 0.8 dB typical insertion loss with 45 dB typical isolation. That balance makes frequency, loss budget, isolation and power handling the main selection axes rather than the package alone.

RF Path Considerations
Nonreflective operation terminates the isolated port, which can reduce impedance discontinuities when switching between RF paths. System insertion loss should still include PCB launches, routing and any external matching structures in addition to the switch itself.
Hot-switching capability is lower than the through-path power rating. A design that changes state while RF power is present should check the manufacturer’s hot-switching limit rather than relying on the static through-path figure.
