The PMB2201 is a modulator and mixer circuit with high integration level. It includes a
direct quadrature modulator and a double balanced Gilbert cell mixer with according bias
circuitry.
The up/down conversion mixer combines two external signals at the RF and IF inputs.
The IF input is suited for the lower frequency signal because of its linear transfer function
to the mixer output. The higher frequency signal is fed to the RF input to switch the
Gilbert cell mixer. In a typical application the wanted mixer output product is bandpass
filtered and then fed to the modulator LO input. The mixer may also be used to convert
the modulator output signal from E/EX via the IF/IFX input by mixing with a local oscillator
signal RF/RFX to higher frequencies up to 2.5 GHz.
The modulator generates two orthogonal carriers which are mixed with the baseband
modulation signals A and B in Gilbert multipliers. The outputs of the Gilbert cells are
added and amplified by a linear output stage. The modulated signal is available at the
open collector output E,EX. The voltage TREF can be used for DC biasing of the
modulation inputs A, AX, B, BX externally.
The modulator and the mixer have separate power supplies and grounds. They can be
powered down independently. Due to the power down concept the modulator can be
used without or in conjunction with the up/down conversion mixer part.
Functional Description
For applications in the frequency range from 1.4GHz to 2.5GHz the derivative PMB2202
is offered.
