RF2942

RF2942 0 Typical Applications 915MHz ISM Band Products Digital Communications Quadrature Modulation Portable Battery-Powered Equipment UHF QUADRATURE MODULATOR AND TRANSMITTER Product Description -A- 2 PLCS 0.25 C A The RF2942 is an integrated power amplifier and quadrature modulator IC. The quadrature modulator is driven with a single-ended local oscillator (LO) source. The quadrature phase generation of the LO is accomplished using an internal passive network tuned for twice the operating frequency. The LO frequency is at twice the RF frequency to avoid interfering with an external synthesizer. 4.00 SQ. 2.00 TYP 0.25 C B 2 PLCS 1.00 0.85 0.80 0.65 0.05 C 0.05 0.01 Dimensions in mm. 12° MAX 0.20 C B 2 PLCS -B- 1.88 TYP 3.75 SQ. -C- SEATING PLANE 2 PLCS 0.20 C A 0.10 M C A B Shaded lead is pin 1. 0.60 0.24 TYP 0.35 0.23 0.65 0.30 4 PLCS 1.85 SQ. 1.55 0.23 0.13 4 PLCS 0.65 0.75 0.50 Optimum Technology Matching® Applied Si BJT Si Bi-CMOS InGaP/HBT GaAs HBT SiGe HBT GaN HEMT GaAs MESFET Package Style: QFN, 16-Pin, 4x4 9SiGe Bi-CMOS I DATATX EN Si CMOS Features 2.0V to 3.6V Power Supply 902MHz to 928MHz Frequency Range 200mW Output Power Low LO Input Level Low Broadband Noise Floor Small Footprint I DATA+ 4 3 12 LO IN+ 14 LO2 OUT 15 ÷2 +45° -45° Σ 9 RF OUT 2 Q DATA+ 1 Q DATA- Ordering Information RF2942 RF2942 PCBA UHF Quadrature Modulator and Transmitter Fully Assembled Evaluation Board Functional Block Diagram RF Micro ...
