| CXG1017N 8 pin SSOP (Plastic) GSM1800/1900 DPDT TX/RX Antenna Switch For the availability of this product, please contact the sales office. Description The CXG1017N is a high power DPDT switch suitable for Digital Cellular applications. 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 JFET process. Features * Positive voltage supply only * Low insertion loss, typically 0.7dB at 33dBm input level * Stable Characteristics over wide temperature range * Fast switching-100ns Typical * Low current consumption, 400A typical at 5.5V * 8 pin SSOP package (3.0 x 6.4mm) Applications * GSM1800 handportable * GSM1900 handportable * DECT basestation/handportable diversity antenna switching * Other digital cellular and wireless local loop applications Typical Application Internal Antenna ESD As with other GaAs semiconductors, ESD precautions must be adhered to.
