Design Notes
The ADL5385ACPZ-R7 requires a clean 5V supply. Use a low-dropout regulator (LDO) with low output noise to avoid degrading the modulator's phase noise performance. Place a 100nF capacitor close to the VCC pin and a 10uF bulk capacitor nearby. Ensure the ground pins are connected to a solid ground plane to minimize parasitic inductance.
For optimal RF performance, use a controlled impedance PCB stack-up. The differential baseband inputs should be routed as differential pairs with 100-ohm differential impedance. The LO inputs should be matched to 50 ohms single-ended or 100 ohms differential as per the datasheet. Keep the RF output trace short and well-matched to 50 ohms. The exposed pad should be soldered to a ground plane with multiple vias for thermal and electrical grounding.
A common pitfall is improper decoupling of the supply pins, which can cause instability and degraded performance. Another is incorrect termination of the differential baseband inputs, leading to I/Q imbalance. Always follow the recommended application circuit in the datasheet. Also, ensure the LO drive level is within the specified range to achieve the best carrier feedthrough and sideband suppression.
