SPDT Switches Work Over DC To 3 GHz Range

Available in very small SOT plastic packages and covering a dc to 3 GHz range, the SW-437 MMIC SPDT reflective switches come in the ultra-miniature SOT-363 package. The SW-442 SPDT terminated switch is available in the SOT-26 package. These switches are well suited for applications requiring low insertion loss, good isolation, and small package size. Uses include portable, dual-band phones where switching between small signal components is required. The devices can be used for applications up to 0.25W, include positive or negative control voltages of 2.5V to 8V, and offer low insertion loss for CDMA, TDMA, GSM and W-CDMA applications.
