Rev A4 010815 RF2689 Preliminary Application Notes Voltage Gain Measurement Set-up The evaluation board uses a unity voltage gain Op-Amp to simulate the 60kΩ differential load impedance condition for the chip. The 50Ω output impedance of Op-Amp makes the use of a 50Ω spectrum analyzer power measurement possible. The power gain measured will be considered as RAW Gain. The input impedance of the chip is 500Ω differential by adding a parallel 680Ω resistor. The input transformer matches 50Ω to 500Ω and results in 10dB difference between voltage gain and power gain, hence, the voltage gain of the chip is RAW Gain minus 10dB. Because the input transformer loss is 0.8dB, it needs to be added to the gain. Since the Op-Amp has the unity voltage gain, the voltage at the evaluation board output is the same as the voltage at chip I or Q output. Therefore, the voltage gain of the chip with 60kΩ load can be calculated by Gv=RAW Gain-10+0.8(dB) Input IP3 Measurement The input IP3 measurement is based on a two tone inter-modulation test condition from the 3GPP standard, which specifies two tones with offset frequencies at 10MHz and 20MHz. Due to the on-chip baseband filtering, the two tone output is attenuated and cannot be seen. Since the only parameter observable is the IM3 product, the input IP3 then is calculated by IIP3=Pin+0.5*(Pin+RAW Gain-IM3) NF=NO +174-RAW Gain-3-0.8(dB) 1dB Gain Compression Point Voltage at Baseband Output The device has a relatively constant 1dB gain compression point versus VGC. Gain compression is tested with a CW signal with 60kΩ load differential. How to Calculate the Power Gain of the Demodulator In the system analysis for cascaded gain, noise and IP, it is often required to calculate the power gain of the demodulator chip itself in matched load condition. Below is an example on how to determine this power gain value. For this example, the load impedance is 60kΩ differential, the output AC impedance of the I or Q port is 500Ω, the measured RAW Gain is 95dB. First, the power gain from the input of the chip to the input of Op-Amp needs to be calculated. Since the voltage at the 50Ω load and the voltage at Op-Amp input are the same, the difference of the power gain across the Op-Amp is the ratio of load impedances. Hence, the power gain to the Op-Amp input is 95dB-10log(60000/50)=95-30=65dB. Second, the power gain of the demodulator itself with matched load is calculated. The mismatch coefficient a is determined by the mismatch coefficient equation 4R S R L 4 ⋅ 500 ⋅ 60000 α = 10 log -------------------------2- = 10 log -------------------------------------2 = – 15dB ( RS + RL ) ( 500 + 60000 ) Rev A4 010815 7-45 QUADRATURE DEMODULATORS 7 Noise Figure Measurement The noise figure measurement is based on the noise figure definition NF=NO -NI -Gain, where NO is the output noise density, NI is the input noise density (-174dBm/Hz when no input signal is applied) and Gain is the RAW Gain. The output noise density NO is measured at 1MHz offset when no signal input is applied. The NF is calculated by NF=NO 174dBm/Hz-RAW Gain. Since the I and Q re-combination will provide 3dB extra for signal-to-noise ratio, the actual noise figure is should be reduced by 3dB. In addition, noise figure should be reduced by the input transformer loss of 0.8dB. Therefore, the NF is calculated by RF2689 Preliminary Since the power gain to the input of the Op-Amp GP’=αGP, where GP is the power gain of demodulator for matched load. Therefore, the demodulator power gain is 65+15 = 80 dB. AC Coupling in Evaluation Board The output I and Q baseband signal is AC coupled for evaluation purposes only. The high-pass corner frequency is at 1/(2π RC)=1/(6.28*30kΩ*100nF)=56Hz. I and Q Output DC Voltage and Its Offset Although the I and Q output is AC coupled on the evaluation board, in most applications, it would be DC coupled to the ADC input buffer. The DC voltage at the IC output is VCC -1.6V with a possible variation of ±0.3V due to temperature and tolerance. The differential circuit asymmetry would cause common mode DC offset to the extent of ±40mV. Baseband Filter Calibration Process The BB (baseband) filter calibration process is same for both WCDMA and GSM/DCS. After calibration is done, the WCDMA mode sets the circuitry to have a 3dB bandwidth of 2.5MHz, the GSM/DCS mode (if the chip has GSM/DCS mode) sets the circuitry to have a 3dB bandwidth of 250kHz. QUADRATURE DEMODULATORS 7 The BB filter in the I and Q path needs to be calculated every time after power down. When the FCLK pin is connected to a signal generator with 0dBm output level at 13.0MHz, a logic high at CALEN pin for 200µs will calibrate the filter to have 2.5MHz bandwidth with 10% accuracy when WCDMA mode is set, or to 250kHz bandwidth with 10% accuracy when GSM mode is set. The calibration is done when the chip is powered on only. Calibration is independent from all other conditions, e.g. the chip enable could be off. The calibration circuitry consumes 400µA. When the calibration sequence is complete after 200µs, the ICC drops to 0mA. The 3dB bandwidth is defined to be from the reference level at 1MHz for WCDMA and at 50kHz for GSM/DCS. The 3dB bandwidth is independent of VGC and VCC. The filter can also be calibrated with different clock frequencies from 10MHz to 30MHz to tune the bandwidth over -40% to +60% from its default 3dB bandwidth (2.5MHz for WCDMA and 250kHz for GSM). The 3dB bandwidth is linear with clock frequency. 7-46 Rev A4 010815 RF2689 Preliminary VREF2V IF+ IF- FCLK * VGC2 Pin Out 20 19 18 17 16 * VGC1 1 15 CALEN GSM IN+ 2 14 I OUT+ GSM IN- 3 13 I OUT- 6 7 8 9 10 EN RX * MODE B 11 Q OUT- LO W-CDMA IN- 5 MODE A 12 Q OUT+ VCC W-CDMA IN+ 4 * * Represents "GND".
