| Preliminary Data Sheet November 1998 W3013 Indirect Quadrature Modulator with Gain Control Features n n n n n n n n Description The W3013 is a monolithic integrated circuit that provides indirect, quadrature modulation of an RF carrier by I & Q baseband inputs. The function performed by the W3013 is particularly suited for handheld digital cellular and digital cordless telephones that operate between 800 MHz and 2.2 GHz. The circuit block diagram is shown below. From a single local-oscillator input (LO1), the phase shifter produces two LO signals with 90 phase separation and equal amplitude. The LO signals are fed to the in-phase (I) and quadrature (Q) double-balanced mixers. The resulting signals are summed and fed into an RF mixer where the frequency can be translated to over 2 GHz. Outputs between the summer and RF mixer are available for external filtering. Finally, the signal is amplified to provide a single-ended output. The ENB/APC input with a logic low allows the device to be put into a powerdown mode. Above the logic low threshold, the device enters a power control mode that provides a range of desired output power levels. Low-voltage operation: 2.7 V High-frequency operation: 2.2 GHz High RF output power: -10 dBm High-accuracy phase shifter, no trim required Low carrier feedthrough: -45 dBc Automatic power control (APC) capability Low-current sleep mode 20-pin TSSOP package Applications n n n n n n North American IS-136 Japan PDC (RCR STD 27) Japan PHS (RCR STD 28) GSM 900, 1800, and 1900 MHz Narrowband CDMA Digital satellite communications I I -/4 LO1 LO1REF +/4 Q Q EXTERNAL FILTER RFOUT O INTERNAL LOW-PASS FILTER RFOUT POWER CONTROL LO2 LO2REF ENAB/APC Figure 1.

Lucent Technologies Microelectronics Group employs a human-body model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used to define the model. No industry-wide standard has been adopted for CDM. However, a standard HBM (resistance = 1500 , capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold presented here was obtained by using these circuit parameters: ESD Threshold Voltage Device W3013 W3013 Rating 1000 V 1000 V Model HBM CDM Lucent Technologies Inc. 3 W3013 Indirect Quadrature Modulator with Gain Control Preliminary Data Sheet November 1998 Operating Ranges This table lists the ranges of external conditions in which the W3013 provides general functionality that may be useful in specific applications without risk of permanent damage.

Lucent Technologies Inc. 5 W3013 Indirect Quadrature Modulator with Gain Control Preliminary Data Sheet November 1998 Error Vector Magnitude (EVM) Testing Error vector magnitude (EVM) is estimated by feeding signals to the W3013 as described at the top of the Electrical Characteristics table. A narrowband, sine-wave modulation output spectrum is shown in Figure 3. 0 -10 RELATIVE MAGNITUDE (dBm) -20 -30 -40 -50 -60 -70 -80 -90 1441.60 1441.68 1441.76 1441.84 1441.92 1442 1442.08 1442.16 1442.24 1442.32 1442.40 L4 L5 -81 dBm -82 dBm L3 -61 dBm L2 -72 dBm CARRIER LSB -50 dBm -53 dBm USB -10 dBm fBB = 80 kHz fLO1= 178 MHz fLO2 = 1620 MHz RFOUT= 1442.08 MHz U2 -63 dBm U3 -71 dBm U5 U4 -77 dBm -84 dBm FREQUENCY (MHz) Figure 3. W3013 Sine-Wave Modulation Output Spectrum Data from this spectrum are used to estimate EVM by the formula: EVM (%) = 100 * [10 10 P(L5)/20 + 10 P(L4)/20 + 10 P(L3)/20 + 10 P(L2)/20 + + 10 P(U5)/20 P(LSB)/20 + 10 P(U2)/20 + 10 P(U3)/20 + 10 P(U4)/20 ]/10 P(USB)/20 The data presented in the spectrum above would yield: EVM (%) = 100 Y [79e-6 + 89e-6 + 891e-6 + 251e-6 + 2239e-6 + 708e-6 + 282e-6 + 63e-6 + 141e-6]/0.316e = 1.5% This approximates worst-case digital modulation results because the sine-wave modulation estimate assumes all spurious outputs are in phase and adds their magnitudes as scalars. In addition, this estimate includes fullamplitude measurements of spurious peaks that would appear in adjacent and alternate channels, where a receiver would otherwise provide attenuation. The L3 third-order intermodulation peak and LSB (lower sideband) are normally the unwanted output frequencies that dominate the EVM estimate. 6 Lucent Technologies Inc. Preliminary Data Sheet November 1998 W3013 Indirect Quadrature Modulator with Gain Control Application Circuits A typical application circuit for the W3013 is shown in Figure 4. The LC filter components, LF and CF, are chosen to have a parallel resonance at the same frequency as LO1, according to the formula fO = 1 2 LF(CF + 1.2e-12) where fO is the center of the filter passband in Hz, LF is the filter inductor in Henries, and CF is the filter capacitor in farads. Use of an inductor of 100 nH or larger in the filter will minimize the variation of output power due to tolerance variation of the filter components. If the transmitter frequency plan requires the use of more than one LO1 frequency, the W3013 RF output power may be approximately equalized by designing the LC filter center frequency at fO = f(LO1max)f(LO1min) , i.e., the geometric mean of the maximum and minimum LO1 frequencies. Board and device parasitic capacitance and inductance must be accounted for in calculating LF and CF. The matching network will vary depending on the application, but must include a series capacitor to block dc connections to the W3013 output pin if the load is conductive. For optimum performance, the bypass capacitor, C1, should have a series self-resonant frequency that is close to the output frequency and should be mounted near pin 20. It is expected that the positive supply (VCC) will appear as a low impedance to ground at low frequencies, using a voltage regulator and/or a large capacitor such as a 10 F tantalum electrolytic. +2.7 V C1 MATCHING NETWORK 1 LF 20 19 18 17 16 15 14 13 12 11 50 (OPT) LO2 ENB/APC z 2 3 4 5 6 7 8 LO1 9 50 (OPT) 10 z OUTPUT CF I I Q Q SIGNALS FROM CODEC Figure 4.

If the voltage on this lead is below VILMAX, the device is in a low-current mode. Between VIHMIN and about VCC, the device draws full supply current and is in a power-control mode.
