It briefly introduced the MAX2450 3V,Uitra-Low-Power Quadrature Modulator/Demodulato. function, internal structure, pin array and typical apply circuit. The MAX2450 combines a quadrature modulator and quadrature demodulator with a supporting oscillator and divide-by-8 prescaler on a monolithic IC. It operates from a single +3V supply and draws only 5.9mA. The demodulator accepts an amplified and filtered IF signal in the 35MHz to 80MHz range, and demodulates it into I and Q baseband signals with 51dB of voltage conversion gain.MAX2450 usully usus for Digital Cordless Phones、GSM and North American Cellular Phones、Wireless LANs、Digital Communications、Two-Way Pagers.
