Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: (1) The VS port 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. All RF 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 VS port may remain open-circuited without damage to the device, but with some degradation in linearity.

Cb are DC blocking capacitors external to the device. A value of 100 pF is sufficient for operation to 500 MHz. The values may be tailored to provide specific electrical responses. The isolation of the switch provides enough decoupling of RF ports 1 through 4 so that overall switch performance is not affected. 2. The VS pin provides a fixed voltage potential to the common port of the switch. To get the best linear performance, it should be tied to the logic high voltage potential (not the power supply). Current draw on this pin is less than 5 A. 3. The RF Ground bondwires should be kept as short as possible and bonded directly to a good RF ground for best broadband performance. 4. LESD 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 125 V 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 >500 V HBM for this technology. By using LESD as an RF choke on a port, an ESD protection to 8 kV contact discharge can be achieved. 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. RF Port 4 Common (Ant.)
