LOW POWER INTEGRATED RECEIVER FOR ISM BAND APPLICATIONS

The ML13145 is a dual conversion integrated RF receiver intended for ISM band applications. It features a Low Noise Amplifier (LNA), two 50 ? linear Mixers with linearity control, Voltage Controlled Oscillator (VCO), second LO amplifier, divide by 64/65 dual modulus Prescalar, split IF Amplifier and Limiter, RSSI output, Coilless FM/FSK Demodulator and power down control. Together with the transmit chip (ML13146) and the baseband chip (MC33410 or MC33411A/B), a complete 900 MHz cordless phone system can be implemented. This device may be used in applications up to 1.8 GHz, and operating temperature TA = –20° to +70°C.

? Low (<1.8 dB @ 900 MHz) Noise Figure LNA with 14 dB Gain

? Externally Programmable Mixer linearity: IIP3 = 10(nom.) to 17 dBm (Mixer1); IIP3 = 10 (nom.) to 17 dBm (Mixer2)

? 50 ? Mixer Input Impedance and Open Collector Output (Mixer 1 and Mixer 2); 50 ? Second LO (LO2) Input Impedance

? Low Power 64/65 Dual Modulus Prescalar (ML12054A type)
