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.
• 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 W Mixer Input Impedance and Open Collector Output (Mixer 1 and
Mixer 2); 50 W 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 W 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 mA)
• 2.4 GHz RF, 1.0 GHz IF1 and 50 MHz IF2 Bandwidth
