PMB 2401
Functional 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.
