RF2483 0 Typical Applications • TDMA/GSM/EDGE Handsets • GSM/EDGE Handsets • W-CDMA Handsets Product Description -A4.00 SQ. RoHS Compliant & Pb-Free Product LOW NOISE DUAL-BAND QUADRATURE MODULATOR WITH AGC • TDMA-Based Wireless Applications • Wireless Local Loop • Basestations 0.10 C A 2 PLCS The RF2483 is a dual-band direct I/Q to RF modulator designed for handset applications where multiple modes of operation are required. The device provides common differential I/Q inputs and a common AGC amplifier. Independent single-ended LO inputs and single-ended high and low band RF outputs are provided. The device achieves a very low out-of-band noise density of -156dBm/Hz minimizing RF filtering. Operating from a single 2.7V supply, the device is assembled in a 4mmx4mm, 20-pin, QFN package. 0.90 0.85 0.05 0.00 0.05 C 2.00 TYP 0.10 C B 2 PLCS 0.70 0.65 12° MAX 0.10 C B 2 PLCS -B1.87 TYP 3.75 SQ. 0.10 C A 2 PLCS SEATING PLANE -CDimensions in mm. 0.10 M C A B NOTES: 1.
