Design Notes
The ADL5385ACPZ requires a clean 5V supply. Use a low-dropout regulator (LDO) with low noise and high PSRR to minimize supply-induced modulation. Place 100 nF and 10 uF decoupling capacitors as close as possible to the VCC pins. The supply current is approximately 300 mA, so ensure the regulator can handle this load with adequate headroom.
For optimal RF performance, use a 4-layer PCB with a solid ground plane. The exposed pad must be soldered to the ground plane with multiple vias for thermal and electrical grounding. Keep the LO input and RF output traces at 50 ohms and as short as possible. Separate the baseband and RF sections to minimize coupling.
Ensure the LO drive level is within 0 dBm to +6 dBm. Insufficient LO drive reduces conversion gain and increases noise, while excessive drive can degrade linearity. Also, the baseband inputs are differential; do not leave them floating. Terminate unused inputs with appropriate resistors to avoid offset and noise.
