Low Power Integrated Receiver

for ISM Band Applications

The MC13145 is a dual conversion integrated RF receiver intended for

ISM band applications. It features a Low Noise Amplifier (LNA), two 50

W

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 (MC13146) and the

baseband chip (MC33410), a complete 900 MHz cordless phone system can

be implemented. This device may be used in applications within 2.0 GHz

since its RF bandwidth is greater than 2.4 GHz.
