PMB2401 GSM Receiver Circuit

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 pur.
