The SW-456 is ideally suited for applications where very low power consumption, low insertion loss, very small size and low cost are required. Typical application is in dual band systems where switching between small signal ponents is required such as filter banks, single-band LNA’s, converters, etc. The SW-456 can be used in applications up to 0.25 watts in systems such as cellular, PCS, DCS1800, GSM, CDMA, W-CDMA and other analog/digital wireless munication systems. The SW-456 is fabricated using a mature 0.8 micron Ga As MESFET process. The process Features full passivation for performance and reliability. Functional Schematic Negative Control Voltage PIN 1 RF1 V1 Handling Procedures The following precautions should be observed to avoid damage: Static Sensitivity Gallium Arsenide Integrated Circuits are ESD sensitive and can be damaged by static electricity. Proper ESD techniques should be used when handling these devices.

External DC blocking capacitors are required on all RF ports. 1000 p F capacitors used for positive control voltage. For higher frequency operation, smaller value DC blocking capacitors can be substituted. 2. If negative control is used,...
