MC13146

The MC13146 is designed as one kind of low power integrated transmitter for ISM band applications. It features a 50 linear Mixer with linearity control, voltage controlled oscillator, divide by 64/65 dual modulus prescaler and exciter. Together with the receiver chip (MC13145) and the baseband chip (MC33410), a complete 900MHz cordless phone system can be implemented. MC13146 may be used in applications within 2GHz since its RF bandwidth is greater than 2.4GHz.

MC13146 has ten features. (1)Low distortion exciter: Pout_1 dB compression point=8dBm. (2)HIgh mixer linearity: IIP3=10dBm. (3)50 mixer input impedance. (4)Differential open collector mixer output. (5)20dB power conversion gain. (6)Low power 64/65 dual modulus prescaler (MC12054 type). (7)2.7 to 6.5V operation, low current drain (25mA at 2.0GHz). (8)Powerdown mode: <1.0mA. (9)2.4GHz RF bandwidth. (10)1.8GHz IF bandwidth. Those are all the main features.

Some absolute maximum ratings of MC13146 have been concluded into several points as follow. (1)Its power supply voltage would be 7V. (2)Its junction temperature would be 150°C. (3)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of MC13146 at Vdd=5V are concluded as follow. (1)Its total supply current enable=Vcc would be typ 25mA. (2)Its power down current enable=Vee would be typ 0.1uA. (3)Its output power with external matching would be typ 0dBm. (4)Its ditortion at 820MHz=fIF_out would be typ 8.0dBm. (5)Its mixer/buffer at 900MHz=fosc would be typ -18dBm. (6)Its output harmonics with external matching at 820MHz would be typ -25dBc for 2nd and would be typ -35dBc for 3rd. (7)Its MC current input optional would be typ 200uAp-p. (8)Its prescalar output level would be typ 0.5Vpp. And so on. If you have any question or suggestion or want to know more information about MC13146 please contact us for details. Thank you!
