MAX23691/Q 2000-800 MHz Dual-Band Tri-Mode Transmitter

MAX2369 is a complete dual-band tri-mode transmitter chip for cellular phones. It is suitable for tri-mode or dual-mode mobile phones, artificial satellites, wireless data links (WAN/LAN), high-speed data modulators, high-speed digital cordless phones and wireless local area networks (WLl.) and other fields. 

The main technical features are as follows: 

・RF operating frequency is 800～1000 MHz/1700～2000 MHz; 

・I/O modulation method; 

・Operating voltage 2.7～ 5.5 V; 

・Power supply current (at VGC = 2.5 V, plus 10 mA local oscillator buffer current): PCS mode is 130 ~ 160 mA, cellular digital mode is 133 ~ 165 mA, FM mode is 115 ~ 143 mA, sleep mode is 20uA; 

・RF output power is 12 dBm for FM mode and 7 dBm for other modes; 

・Power control range is 30 dB (VGC = 0.5 ~ 2.5 V); 

・Working temperature: -40～85℃; 

・It has a 3-wire serial bus compatible with SPITM/QSPITM/MICROWIRETM; 

・Single sideband up-conversion eliminates the need for SAW filters.
