Low Power Integrated Transmitter for ISM Band Applications

The MC13146 is an integrated RF transmitter targeted at ISM band applications. It features a 50 Ω linear Mixer with linearity control, voltage controlled oscillator, divide by 64/65 dual modulus Prescaler and Low Power Amplifier (LPA). Together with the receiver chip (MC13145) and either baseband chip (MC33410 or MC33411A/B), a complete 900 MHz cordless phone system can be implemented. This device may be used in applications up to 1.8 GHz.
