1 Typical specifications tested at 25°C with VDD = 3.3V.

2 RFxx is RF1A, RF1B, RF2A, and RF2B. RFCx is RFCA or RFCB. INx is IN1, IN2, IN3, and IN4.

3 This value shows the time it takes for 1% of a sample lot to fail.

4 Switch is settled after 200µs. Do not apply RF power between 0µs to 200µs.

5 RF power should be removed or less than 5dBm, 50µs before turning the switch off.

6 Spectrum analyzer setup: resolution bandwidth (RBW) = 200Hz, video bandwidth (VBW) = 2Hz, span = 100kHz, input attenuator = 0dB, detector type = peak, and max hold

= off. Measurements taken with one switch on and off switch port terminated into 50 Ω. The fundamental feedthrough noise or harmonic thereof is tested (whichever is the

highest).

7 The on leakage and off leakage specifications depend on the DC voltage level applied to the switch node. For example, if 1V is applied at RFxx to RFCx, the on leakage

specification is 0.2µA and off leakage specification is 0.1µA. The leakage specification of the switch is mainly driven by the internal 10MΩ resistors to ground connected on

all the RF nodes to avoid floating nodes.
