The MC13145 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 (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.

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

• Externally Programmable Mixer linearity: IIP3 = 10(nom.) to +20 dBm

(Mixer1); IIP3 = 10 (nom.) to 20 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 (MC12053 type)

• Split IF for Improved Filtering and Extended RSSI Range

• Internal 330



Terminations for 10.7 MHz Filters

• Linear Coilless FM/FSK Demodulator with Externally Programmable

Bandwidth, Center Frequency and Audio level

• 2.7 V to 6.5 V Operation, Low Current Drain (<30 mA @ 3.0 V) with

Power Down Mode (<1.0 A)

• 2.4 GHz RF , 1.0 GHz IF1 and 50 MHz IF2 Bandwidth
