PRODUCT DESCRIPTION
The AWS5523 is a single pole, three terminal (SP3T) RF switch developed to meet the stringent requirements of GSM systems. Manufactured in ANADIGICS's state-of-the-art pHEMT process, the device uses patent-pending circuit topologies to provide the low insertion loss, high port-to-port isolation and high linearity needed to enhance the performance of GSM radios. The AWS5523 is offered as an unpackaged MMIC die.

Stresses in excess of the absolute ratings may cause permanent damage. 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.

The device may be operated safely over these conditions; however, parametric performance is guaranteed only over the conditions defined in the electrical specifications. 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.

APPLICATION INFORMATION
Die Applications Bonding and circuit connections for the unpackaged AWS5523 die are shown in Figure 8, and application details are listed in the following notes: 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. 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 5A. 3. The RF Ground bondwires should be keep 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 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. 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.
