Package Style: LCC, 32-Pin, 5x5 GaAs MESFET üSiGe HBT Si Bi-CMOS 5.00 sq. FRONT-ENDS The RF2492 is a fully featured dual-band LNA/Mixer and is usable in a variety of mobile handset applications. The unique dual IF outputs provide interface to two independent IF SAW filters supporting applications such as TDMA-EDGE where 30kHz and 200kHz bandwidth SAW filters are used. With independent power management control pins for the LNAs and mixers, either IF output can be accessed from either high- or low-band LNAs, providing maximum flexibility with minimum power usage. Multiple gain control options are provided to achieve a very large dynamic range for the receiver. A frequency doubler is included in the LO circuit to generate both high- and low-band LO signals with a single VCO. The RF2492 is packaged in a 32 pin, 5mmx5mm, leadless plastic package. 0.80 0.65 Features Si CMOS • Complete Dual-Band Receiver Front End • Low Noise Figure 4 IF1+ 5 IF1- 7 IF2- 8 IF2+ PCS LNA IN 30 LNA GAIN SEL 12 MIX GAIN SEL 14 • Stepped LNA/Mixer Gain Control • Adjustable LNA Bias Current/IIP3 • Integrated LO Frequency Doubler CELL LNA IN 11 • Differential LO Buffer Outputs 19 PCS LO OUT+ IF SEL 9 20 PCS LO OUT - LNA IP SEL 10 LNA ISET 17 X2 LOGIC CONTROL Ordering Information X2 ENABLE 32 15 18 1 LO IN CELL MIX IN CELL LNA OUT Functional Block Diagram Rev A4 010828 21 CELL LO OUT+ 22 CELL LO OUT- BAND SEL 31 RF2492 RF2492 PCBA Dual-Band Low Noise Amplifier/Mixer Fully Assembled Evaluation Board RF Micro Devices, Inc. 7625 Thorndike Road Greensboro, NC 27409, USA Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com 8-33 RF2492 Preliminary Absolute Maximum Ratings Parameter Supply Voltage Input LO and RF Levels Operating Ambient Temperature Storage Temperature Parameter Rating Unit -0.5 to +5.0 +6 -40 to +85 -40 to +150 VDC dBm °C °C Specification Min.
