Product Description
2.1 Overview
The PMB 2208 contains a direct quadrature modulator and an up/down-conversion mixer with corresponding bias circuitry. The modulator splits the signal at the LO/LOX input into two orthogonal carriers. The frequency of these carriers is half of the LO/LOX input frequency. The carriers are multiplied with the baseband modulation signals at the A/AX and B/BX inputs. The outputs of the multipliers are added and amplified by a linear output stage. The modulated signal is available at the E/EX output. A reference voltage is available at the TREF output, which can be used to bias the baseband inputs. The mixer combines the signals at the RF/RFX and IF/IFX inputs; the resulting signal is available at the MO/MOX output. The IF/IFX input is suitable for the lower-frequency signal because of its linear transfer function to the output. The higher-frequency signal is applied to the RF/RFX input, which operates in switched mode. In a typical application, the output signal of the modulator is band-pass filtered and then fed to the IF/IFX input of the mixer. The modulator and mixer have separate power supplies, and can be powered down independently. The power-down concept enables the modulator to be used with or without the mixer.

3.5 Circuit Description
The modulator performs a direct quadrature modulation. The LO signal is connected to an emitter-coupled transistor pair. The LO signal is split internally into two orthogonal carriers at half of the LO/LOX input frequency. The accuracy of the internal 90 phase shift requires a balanced input signal and depends on the accuracy of the 50% duty cycle of the LO/LOX signal. The modulator has two Gilbert cell mixers, in which the baseband modulation signals at the A/AX and B/BX inputs are multiplied with the orthogonal carriers. The outputs of the two Gilbert cells are added and amplified by a linear output stage. The modulated transmit signal is available at the high-impedance, open-collector output E/EX. It can be band-pass filtered and fed to the IF/IFX input of the mixer. At the TREF output, a reference voltage is available, which should be capacitively decoupled to ground. TREF can be used to set the DC bias of the baseband inputs using external resistors. Alternatively, the DC level can be set independently of TREF, provided it is within the specified operational range. The up/down-conversion mixer is a fully-balanced Gilbert cell. The transfer function from the low-impedance emitter input IF/IFX to the output is linear for input levels below the 1dB compression point. For improved intermodulation, the mixer current can be increased with external resistors to ground at IF/IFX. The high-impedance input RF/RFX is directly connected to the bases of the switching transistors. The input level should be high enough to ensure proper switching. The output signal of the mixer is available at the high-impedance, open-collector outputs MO/MOX. The modulator and the mixer have separate supply and power-down pins: VCC1, PD1 for the modulator and VCC2, 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.

The mixer current decreases when no external resistors to ground are connected at IF and IFX. In this case the typical value of ,MO+,MOX is 1mA. Design hint. The settling time is determined by the time required to charge the external capacitors. Note: There are external resistors (82 Ohms) at IF and IFX to ground. Application hint Design 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 926$ and 926%, the carrier suppression in dB is given by

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.
Table 5-4 Test RF-Input impedance IF-Input impedance MO-Output impedance Frequency [MHz] 50 - 2500 50 - 2500 50 - 2500 Port 1 RF IF MO Port 2 RFX IFX MOX Output levels -5 dBm -30 dBm -30 dBm
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 a resistor Rp parallel to a capacitance Cp is derived:
Rpd
