Key Differentiators
- Dual-polarization support (vs ADMV4820)
- 16 TX and 16 RX channels (vs ADMV4822)
- Wide frequency coverage (vs ADMV4820)
Design Notes
The ADMV4821C dissipates significant power due to its 32 RF channels. Ensure adequate heat sinking and thermal vias in the PCB layout. Refer to the thermal resistance values in the datasheet, which are simulated based on JEDEC specifications (JESD51-12).
For optimal RF performance, use a high-frequency laminate with controlled impedance. Keep RF traces as short as possible and match them to 50 ohms. Place decoupling capacitors close to the power pins to minimize noise.
Ensure the control interface is properly configured for beam steering. Incorrect register settings can lead to phase errors. Also, verify the power supply sequencing to avoid latch-up.
