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 components 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 communication systems. The SW-456 is fabricated using a mature 0.8 micron GaAs MESFET process. The process features full passivation for performance and reliability.

External DC blocking capacitors are required on all RF ports. 1000 pF capacitors used for positive control voltage. For higher frequency operation, smaller value DC blocking capacitors can be substituted. 2. If negative control is used, DC blocking capacitors are not required on RF ports.
