CXG1121TN

CXG1121TN SP4T GSM/GPRS Dual-Band Antenna Switch + Logic Description The CXG1121TN is one of a range of low insertion loss, high power MMIC antenna switches for GSM/ GPRS dual-band application. The low insertion loss on transmit means increased talk time as the Tx power amplifier can be operated at a lower output level. On-chip logic reduces component count and simplifies PWB layout by allowing direct connection of the switch to digital base band control lines with CMOS logic levels. This switch is an SP4T, one antenna can be routed to either of the 2 Tx or 2 Rx ports. It requires 3 CMOS control lines (Tx/Rx, GSM900/1800 and Standby). The Sony GaAs JFET process is used for low insetion loss. An evaluation PWB is available. Features Insertion loss (Tx) 0.5dB typical at 34dBm (GSM900) 3 CMOS compatible control lines Low second harmonic, –40dBm typical, at 34dBm (GSM900) Small package size: 16-pin TSSOP (3.9mm × 4.1mm × 1.2mm) Applications Dual-band handsets using combinations of GSM900/GSM1800/GSM1900 GPRS class 12 handsets Structure GaAs J-FET MMIC 16 pin TSSOP (Plastic) Absolute Maximum Ratings (Ta = 25°C) Bias voltage VDD 7 Control voltage VCTL 5 Operating temperature Topr –20 to +80 V V °C GaAs MMICs are ESD sensitive devices. Special handling precautions are required. The IC will be damaged in the range from 100 to 200V @200pF 0Ω and below 1000V @100pF 1500Ω.
