| CXG1008N High Isolation SPDT Switch For the availability of this product, please contact the sales office. Description The CXG1008N is a high isolation SPDT switch suitable for Digital Cellular applications, Cable TV and so on. This device is part of a growing family of MMIC Antenna switches for digital cellular and cordless radios. It uses the state-of-the-art Sony GaAs JFET process. Features * Positive voltage supply only * Ultra high isolation, typically 58 dB (GSM 900) * Low insertion loss, typically 0.7 dB at 20 dBm input level (GSM 900) * Stable Characteristics over wide temperature range * Fast switching-50 ns Typical * Low current consumption, 50 A typical at 3.0 V * 8 pin SSOP package (3.0 x 6.4 mm) Applications * Basestation LO switching (GSM900/1800/1900, PHS) * Other Low Power SPDT applications requiring high isolation (e.g. Cable TV) 8 pin SSOP (Plastic) ESD As with other GaAs semiconductors, ESD precautions must be adhered to.
