Integrated balun and hybrid couplers allow high performance RF capability over a frequency range of 0.5 GHz to 1.0 GHz. EVALUATION KIT CONTENTS ADL6316-EVALZ evaluation board ADDITIONAL HARDWARE REQUIRED Analog signal generator Analog signal analyzer Power supplies (6 V, 5 A) PC with Windows(R) XP, Windows 7, or Windows 10 operating system USB 2.0 port, recommended (USB 1.1-compatible) EVAL-SDP-CS1Z (SDP-S) controller board ADDITIONAL SOFTWARE REQUIRED To optimize performance vs. power level, the ADL6316 includes a voltage variable attenuator (VVA), high linearity amplifiers, and a digital step attenuator (DSA). The devices integrated into the ADL6316 are programmable via a 4-wire serial port interface (SPI). This user guide describes the evaluation board and software for the ADL6316.

Figure 2 shows the typical bench setup to evaluate the performance of the ADL6316. RF OUTPUTS The RF outputs are available on the evaluation board at the RF_OUT SMA connectors, which can drive a load of 50 . SIGNAL PATH MODES SELECTION POWER SUPPLY The ADL6316 has two signal path modes. This feature allows two predefined modes of operation to be controlled by the logic level on TXEN, a real-time external pin (Pin 37), without SPI latency. Table 1 shows the hardware configuration to select the desired mode. The ADL6316-EVALZ evaluation board requires a single, 5.0 V power supply. RF INPUT The on-board balun enables single-ended driving. The ADL6316 operates the 0.5 GHz to 1.0 GHz frequency range. USB VVA CONTROL VOLTAGE GND RF INPUT RF OUTPUT GND 21832-002 +5.0V Figure 2.
