Description

The PMB 2201, 2202 family is a direct quadrature modulator and double balanced mixer. PMB2202 is fabricated using Siemens B6HF silicon bipolar process. In a typical application the wanted mixer output product is bandpass filtered and then fed to the modulator LO input. The mixer PMB2202 may also be used to upconvert the modulator output signal to higher frequencies up to 2.5 GHz.

The modulator generates two orthogonal carriers which are mixed with the baseband modulation signals by two multipliers. The outputs of the multipliers of PMB2202 are added and amplified by a linear output stage. The modulator and the mixer have separate power supplies and grounds. They can be powered down independently.
