The SW-437 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-437 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 communications systems. The SW-437 is fabricated using a mature 0.8 micron GaAs MESFET process. The process features full passivation for increased performance and reliability.2X PIN 1.0492 1,25##X-A-.0827 2,1-D10° 4° .0079 (0.20) C 8° 0° 10° 4°.0059 (0.15) C .0118 .0059 0,30 0,152X.0433 MAX 1,10 .0354 +.0038 -.0079 0,90 +0,10 -0,20 -C.0039 .0000 0,10 0,00.0039 (0.10) M B C A B D.0039 (0.10) C 2X1.
