General Description

The PMB 2401 is a single-chip single-conversion heterodyn PM-receiver with phase shifting circuitry for the I/Q-phase baseband demodulation on chip.

It also includes the second local oscillator, a gain controlled second IF-amplifier, two differential operational amplifiers for baseband filtering purposes and power down circuitry.

The PMB 2401 is designed for digital mobile telephones according to the GSM-standard and other digital systems.

Key Features

q Heterodyne receiver with demodulator q Down mixing from 900 MHz receiver band to the base q q q q q q q q q q q q band Demodulation and generation of I/Q-baseband components Low mixer noise 10 dB (SSB) Input high intercept point + 2 dB Integrated 0˚ and 90˚ phase shifter 82 dB AGC-range On-chip second LO-oscillator with external tuning circuit Two differential operational amplifiers Low power consumption due to highly flexible powerdown capability Wide input frequency range up to 1 GHz Wide I.
