Description Ro HS pliant & Pb-Free Product LOW NOISE, MULTI-MODE, QUAD-BAND, QUADRATURE MODULATOR AND PA DRIVER - W-CDMA/GSM/EDGE Multimode Handsets and Data Cards -A-B- 1.00 0.80 The RF2705 is a low noise, multi-mode, quad-band direct I/Q to RF modulator and PA driver designed for handset applications where multiple modes of operation are required. Frequency doublers, dividers and LO buffers are included to support a variety of LO generation options. Dynamic power control is supported through a single analog input giving 90d B of power control range for the W-CDMA mode and 40d B of power control in the other two modes. Three sets of RF outputs are provided: high band and low band low noise EDGE/GMSK outputs, as well as one wideband W-CDMA output. The device is designed for 2.7V to 3.3V operation, and is assembled in a plastic, 24-pin, 4mmx4mm QFN. 0.10 C 0.10 C B 2 PL 0.10 C A 2 PL 0.2 C Shaded area indicates pin 1.
