Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: (1) The VS1 and VS2 ports may remain open-circuited without damage to the device. (2) Storage Temperature limits apply to the die only after it has been removed from the ANADIGICS shipping material. 3. The RF1, RF2, RF3 and RFC ports should be AC-coupled. No external DC bias should be applied.

Notes: (1) For optimal linearity performance, the Common Port Bias Voltage (VS) should be set to the same Control Voltage used to turn ON any of the individual RF paths. The VS1 and VS2 ports may remain open-circuited without damage to the device, but with some degradation in linearity.

The RF Ground bondwires should be keep short as possible and bonded directly to a good RF ground for best broadband performance. 1. Cb are DC blocking capacitors external to the device. A value of 100pF is sufficient for operation to 500MHz. The values may be tailored to provide specific electrical responses. The isolation of the switch provides enough decoupling of RF ports 1 through 3 so that overall switch performance is not affected. 4. L ESD provides a means to increase the ESD protection on a specific RF port, typically the port attached to the antenna. The ESD rating of the device is ±125V HBM overall. This rating is associated with the control pin to RF port path. RF port to RF port/RF Gnd has been determined to be >±500V HBM for this technology. By using LESD as an RF choke on a port, an ESD protection to ±8kV contact discharge can be achieved. 2. The VS1 and VS2 pins provide a fixed voltage potential to the common port of the switch. To get the best linear performance, either VS1 or VS2 must be tied to the logic high voltage potential (not the power supply). Only one of the pins need be attached, with the decision determined by external circuit layout. Currentdraw on this pin is less than 5µA. 5. The die may be attached by either conductive or non-conductive epoxy formulated for attaching semiconductor parts. The back of the die is electrically isolated from the switch circuit and can be grounded or left isolated. Common (Ant.)
