Functional Description
The PMB2202 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.
For applications in the frequency range from 800MHz to 1.5GHz the derivative PMB2201
is offered.

Circuit Description
Block Level Description
The PMB2202 includes an up/down conversion mixer and a direct quadrature modulator
on one chip.
The mixer is a fully balanced Gilbert cell. The IF, IFX pins are low impedance inputs. The
transfer function from this input to the mixer output is linear for input levels below the 1dB
compression point. For improved intermodulation the mixer current can be increased
with external resistors to GND2 at IF, IFX. The RF, RFX pins are high impedance inputs
and are DC coupled to the bases of the transistors in the Gilbert cell. The input level at
RF, RFX should be high enough to ensure proper switching of the differential transistor
pairs. The mixer output pins MO, MOX are high impedance open collector outputs. The
wanted mixer output product can be band pass filtered and fed to the LO,LOX input of
the modulator or to an external load.
The LO, LOX pins are the high impedance inputs of an emitter coupled differential pair.
The LO signal is internally divided into two orthogonal carriers at the transmit frequency.
The modulator has two Gilbert cell multipliers, in which the modulation signals A(t) and
B(t) are mixed with the orthogonal carriers. The outputs of both Gilbert cells are added
and amplified by a linear output stage. The modulated transmit signal is available at the
high impedance open collector outputs E/EX and can be fed to a power amplifier.
At the output TREF a DC voltage for biasing the modulation inputs A, AX, B, BX is
available, which should be capacitively decoupled to ground. The modulation inputs can
be connected externally via bias resistors to TREF. Due to the low voltage concept a
balanced drive of the differential modulator inputs is recommended to obtain the best
second and third order spurious suppression.
The phase adjust input ADJ allows the single sideband suppression of the modulator to
be optimized for a particular application. If the specified sideband suppression is
sufficient, ADJ should only be capacitively decoupled to ground, in which case the
voltage at ADJ is set internally to half the TREF voltage. If a higher suppression is
required, the voltage at ADJ can be adjusted to the optimum value by a pull-up resistor
to TREF, a pull-down resistor to GND1 or a potentiometer between TREF and GND1.
The modulator and the mixer have separate supply, ground and power down pins:
VCC1, GND1, PD1 for the modulator and VCC2, GND2, PD2 for the mixer. Applying a
logic LOW to PD1 or PD2 powers down the corresponding part of the chip, including its
bias circuitry. Depending on the application the power down pins can be combined or
separately fixed to supply rails.

AC/DC characteristics involve the spread of values guaranteed within the specified
supply voltage and ambient temperature range. Typical characteristics are the median
of the production.
Supply voltage VVCC = 2.7V...4.5V, Ambient temperature Tamb = +25°C

* Application hint
** The carrier suppression can be optimized for a particular application using offset voltages at the baseband
inputs A/AX and B/BX. The optimum values can be found iteratively by adjusting the A/AX and B/BX offsets
alternately until the carrier disappears into the noise floor. If the actual offset voltages differ from their optimum
values by ∆VOSA and ∆VOSB, the carrier suppression in dB is given by
Vm
a c = 20 ⋅ log 10 ------------------------------------------------------------2
2
( ∆V OSA ) + ( ∆V OSB )
where Vm is the peak value of the signal voltage at A/AX and B/BX.
*** Phase adjust pin ADJ not used.
**** aIM3 can be increased by reducing the amplitude of the modulator inputs VA-AX and VB-BX.

S-Parameters and Input/Output Impedances
The S-parameters provided in this section are based on measurements at the supply
voltage of VCC = 3.6V. Via the internal bias tees of the NWA the capacitive coupling is
done and the open collector pins are connected to VCC.
The S-parameters have to be considered as application hints.

The input/output impedances are calculated from these parameters. The impedances
are given as equivalent circuit with lumped elements for differential and single ended in/outputs.
As equivalent circuit for these in-/outputs (except IF) a resistor Rp parallel to a
