ML13145
UHF Wideband Receiver Subsystem
(LNA, Mixer, VCO, Prescaler, IF
Subsystem, Coiless Detector)
LOW POWER INTEGRATED RECEIVER FOR ISM BAND APPLICATIONS
SEMICONDUCTOR TECHNICAL DATA
Legacy Device: Motorola MC13145
The ML13145 is a dual conversion integrated RF receiver intended for ISM
band applications. It features a Low Noise Amplifier (LNA), two 50 Ω 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 con-
trol. Together with the transmit chip (ML13146) and the 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,
