All 4 ports of the switch have identical electrical and linearity performance which allows flexibility in system design. Switching between ports is accomplished using 2.7 to 6 volts differential control voltages on the 4 control pins. The switch is provided in a leadless MLP-16 quad flat package. 1. DC blocking capacitors Cb and optional resistor Rs must be supplied externally. 2. Cb = 100 pF for operation >500MHz. 3. The use of resistor Rs to the positive voltage supply is optional. It is only required if it is necessary to have all RF ports in Isolation state at the same time. Also, using Rs will improve linearity performance to a small degree when VCTL is at its lower limit. Rs = 10k Ω when used.
