1 / 6 page MC13145 UHF WIDEBAND RECEIVER SUBSYSTEM (LNA, Mixer, VCO, Prescalar, IF Subsystem, Coilless Detector) FTA SUFFIX PLASTIC PACKAGE CASE 932 (LQFP–48) 48 1 Order this document by MC13145/D Device Temperature Range Package ORDERING INFORMATION XC13145FTA –40 ° to +85°C LQFP– 48 ESD Sensitive — Handle with Care 1 MOTOROLA RF/IF DEVICE DATA Product Preview 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 PIN CONNECTIONS AND FUNCTIONAL BLOCK DIAGRAM VEE BWadj Lim Dec2 Lim Dec1 Lim In VCC VCC IF Out VEE LNA In VEE VEE LNA Out VEE Mxr1In Lin Adj1 13 14 15 16 18 19 20 48 47 46 45 44 43 42 41 25 26 29 30 31 32 27 28 12 11 8 7 6 5 10 9 Enable oscC oscE oscB 43 2 1 33 34 35 36 IF Dec2 IF Dec1 IF In VEE 40 39 38 37 17 21 22 23 24 Lim Demod LNA /64, 65 S IF LO RF IF2 IF1 This document contains information on a product under development.
