EVALUATION BOARD HARDWARE
The ADL6316-EVALZ evaluation board provides the support
circuitry required to operate the
ADL6316 in various modes and
configurations. Figure 2 shows the typical bench setup to
evaluate the performance of the
ADL6316 .
POWER SUPPLY
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.
RF OUTPUTS
The RF outputs are available on the evaluation board at the
RF_OUT SMA connectors, which can drive a load of 50 Ω.
SIGNAL PATH MODES SELECTION
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.
