The ADRF5730BCCZN is a high-performance, monolithic digital step attenuator (DSA) manufactured by Analog Devices. Designed for RF and microwave applications, it provides precise, digitally controlled attenuation of radio frequency signals with excellent linearity and low insertion loss, making it suitable for wireless communication systems, test equipment, and radar systems.

• Attenuation Range: 0 dB to 31.5 dB, covering a wide range of signal strength adjustment needs.
• Step Size: 0.5 dB, enabling fine-grained control over signal levels for precise calibration and optimization.
• Attenuation Accuracy: ±0.5 dB (typical) across the entire range, ensuring reliable and consistent signal attenuation.
• Frequency Range: 100 MHz to 6000 MHz (100 MHz to 6 GHz), supporting a broad spectrum of RF and microwave applications including cellular (5G/4G), Wi-Fi, and satellite communications.

• Insertion Loss: Typically 1.8 dB at 2 GHz and 2.8 dB at 6 GHz, minimizing signal degradation when the attenuator is in the minimum attenuation state (0 dB).
• Return Loss: Better than 15 dB (typical) across the frequency range, ensuring good impedance matching to 50 Ω systems and reducing signal reflections.
• Linearity: Excellent linearity with IP3 (Third-Order Intercept Point) of +48 dBm (typical), making it suitable for high-power signal environments without significant distortion.
• Power Handling: Up to +27 dBm (500 mW) average power, allowing operation in high-power RF systems.

• Digital Control: Serial Peripheral Interface (SPI) with 16-bit command structure, enabling easy integration with microcontrollers (MCUs) and digital signal processors (DSPs).
• Control Pins: Features chip select (CS), serial clock (SCLK), and serial data (SDATA) pins for straightforward digital control.
• Power-Up State: Configurable power-up state (last state retention or default to 0 dB attenuation), providing flexibility in system initialization.
• Fast Switching Speed: Typical switching time of 100 ns, allowing rapid adjustment of attenuation levels for dynamic signal environments.

• Power Supply Voltage: 3.0 V to 5.5 V, compatible with standard digital logic levels and RF system power supplies.
• Power Consumption: Low current consumption of 3 mA (typical) during operation, and 10 µA (typical) in shutdown mode, making it suitable for power-constrained applications.
• Package: 16-lead LFCSP (Lead Frame Chip Scale Package) with exposed pad, measuring 3 mm * 3 mm. This compact package offers excellent thermal performance and is suitable for space-constrained RF designs.
• Operating Temperature Range: -40°C to +85°C, ensuring reliable operation in industrial and harsh environmental conditions.
