Typical Applications
ADAR4002 is suitable for 6 applications: Phased Array Radar, Electronic Warfare, 5G Beamforming, Test and Measurement, Satellite Communication, Radar Test Systems.
Phased Array Radar
The ADAR4002 provides true time delay for beam steering in phased array radar systems. Its wideband operation (0.5-19 GHz) and bidirectional capability make it ideal for T/R modules. The low power consumption is beneficial for large arrays. The SPI interface allows precise control of delay and attenuation for each element.
Recommended
Electronic Warfare
In electronic warfare, the ADAR4002 is used for signal delay and attenuation to simulate or counter threats. Its wideband frequency range and fast state switching via the UPDATE pin enable rapid response. The bidirectional operation supports both receive and transmit paths, making it versatile for EW systems.
Recommended
5G Beamforming
The ADAR4002 is suitable for 5G beamforming, where true time delay is required to maintain signal integrity across wide bandwidths. Its 0.5-19 GHz range covers sub-6 GHz and mmWave bands. The compact package and low power consumption are ideal for small cell and massive MIMO systems.
Recommended
Test and Measurement
The ADAR4002 can be used in test equipment to introduce precise time delays and attenuation for calibration and characterization. Its SPI interface allows automated control, and the 50 Ξ© matched ports simplify integration into test setups. The wideband operation supports a variety of RF measurements.
Recommended
Satellite Communication
In satellite communication, the ADAR4002 provides time delay and attenuation for beamforming and signal conditioning. Its wideband operation covers C, X, Ku, and Ka bands. The low power consumption is critical for space-constrained satellite payloads.
Recommended
Radar Test Systems
The ADAR4002 is used in radar test systems to simulate target echoes with precise time delay and attenuation. Its bidirectional operation allows testing of both transmit and receive paths. The memory states enable pre-programmed scenarios for automated testing.

- Single-channel design (vs ADAR4001)
- Bidirectional operation (vs ADAR4001)
Design Notes
Ensure proper RF layout with 50 Ξ© controlled impedance traces for RF1 and RF2 ports. Place decoupling capacitors close to the VDD pin and use a solid ground plane. The exposed pad should be soldered to the ground plane for thermal and electrical performance.
The ADAR4002 is a low power device, but ensure the supply voltage is within the recommended range. Use a low-noise LDO to power the device to avoid noise coupling into the RF path. Decouple the supply with 100 nF and 10 Β΅F capacitors.
Avoid exceeding the maximum frequency range of 19 GHz. Ensure the control interface (SPI or shift register) is correctly configured to avoid unintended state changes. The UPDATE pin should be used carefully to advance memory states only when needed.
