TQ3132

WIRELESS COMMUNICATIONS DIVISION C2 Control Logic C2 L1 TQ3132 DATA SHEET VDD GND GND RF IN RF 50 ohm OUT RF Out Control Logic Low Current, 3V Cellular Band CDMA/AMPS LNA IC GND C3 Features Small size: SOT23-8 Single 3V operation Product Description The TQ3132 is a low current, 3V, RF LNA IC designed specifically for Cellular band CDMA/AMPS applications. It’s RF performance meets the requirements of products designed to the IS-95 and AMPS standards. The TQ3132 is designed to be used with the TQ5131 or TQ5132 (CDMA/AMPS mixer) which provides a complete CDMA receiver for 800MHz dual-mode phones. The LNA incorporates on-chip switches which determine CDMA, AMPS, and bypass mode select. When used with the TQ5131 or TQ5132 (CDMA RFA/mixer), four gain states are available. The RF output port is internally matched to 50 Ω, greatly simplifying the design and keeping the number of external components to a minimum. The TQ3132 achieves good RF performance with low current consumption, supporting long standby times in portable applications. Coupled with the very small SOT23-8 package, the part is ideally suited for Cellular band mobile phones.
