... ADL5387 CIRCUIT DESCRIPTION The ADL5387 can be divided into five sections: the local oscillator (LO) interface, the RF voltage-to-current (V-to-I) converter, the mixers, the differential emitter follower outputs, and the bias circuit. A detailed block diagram of the device is shown in Figure 45. BIAS RFIP DIVIDE-BY-TWO QUADRATURE ...

... BASIC CONNECTIONS Figure 47 shows the basic connections schematic for the ADL5387. POWER SUPPLY The nominal voltage supply for the ADL5387 and is applied to the VPA, VPB, VPL, and VPX pins. Ground should be connected to the COM, CML, and CMRF pins. Each of the supply pins should be decoupled using two capacitors; ...

... ADL5387 RF INPUT The RF inputs have a differential input impedance of approximately 50 Ω. For optimum performance, the RF port should be driven differentially through a balun. The recommended balun is M/A-COM ETC1-1-13. The RF inputs to the device should be ac-coupled with 1000 pF capacitors. Ground-referenced choke inductors must also be connected to RFIP and RFIN (recommended value = 120 nH, Coilcraft 0402CS-R12XJL) for appropriate biasing ...

... Figure 51 shows typical EVM performance over input power range for a point-to-point application with 16 QAM modulation schemes and zero-IF baseband. The differential dc offsets on the ADL5387 are in the order of a few mV. However, ac coupling the baseband outputs with 10 μF capacitors helps to eliminate dc offsets and enhances EVM performance. With a 10 MHz BW signal, 10 μ ...

... It is necessary to consider the overall source and load impedance presented by the ADL5387 and ADC input to design the filter network. The differential baseband output impedance of the ADL5387 is 50 Ω. The ADL5387 is designed to drive a high impedance ADC input. It may be desirable to terminate the ADC input down to lower impedance by using a terminating resistor, such as 500 Ω ...

... As an example, a second-order, Butterworth, low-pass filter design is shown in Figure 56 where the differential load impedance is 500 Ω, and the source impedance of the ADL5387 is 50 Ω. The normalized series inductor value for the 10-to-1, load-to- source impedance ratio is 0.074 H, and the normalized shunt capacitor is 14.814 F. For a 10.9 MHz cutoff frequency, the single-ended equivalent circuit consists of a 0.54 μ ...
