1. Refer to "Tape and Reel Packaging" Section, or contact factory. 2. All specifications apply when operated with bias voltages of 0V for Vin Low and to 10V for Vin Hi, and 50 Ohm impedance at all RF ports, unless otherwise specified. High power (greater than 1W) handling specifications apply to cold switches only. For input powers under 1W, hot switching can be used. The high control voltage must be within 0.2V of the supply voltage. The RF ports must be blocked outside of the package from ground or any other voltage.
