Analog Devices Inc. ADRF5714BCCZN-R7

Overview

ADRF5714BCCZN-R7 from Analog Devices is a silicon-based 1-bit digital RF attenuator delivering precisely 16 dB attenuation across 100 MHz to 30 GHz, with ≤1.3 dB insertion loss at 30 GHz, ±0.20 dB attenuation accuracy up to 30 GHz, and CMOS-/LVTTL-compatible D0 control. It serves as a high-frequency amplitude control element in millimeter-wave signal paths for 5G infrastructure and test instrumentation.

For engineers reviewing the ADRF5714BCCZN-R7 datasheet, ADRF5714BCCZN-R7 pinout, ADRF5714BCCZN-R7 application, or ADRF5714BCCZN-R7 equivalent, key selection criteria include ultrawideband frequency coverage, single-supply operability (VDD = 3.3 V, VSS = GND), RF power handling (30 dBm avg), settling time (110 ns @ 0.1 dB), and LGA package thermal performance (θJC = 50°C/W).

Technical Context

The ADRF5714BCCZN-R7 implements a monolithic silicon switch-attenuator topology with DC-coupled 50 Ω RF ports (ATTIN/ATTOUT), enabling bidirectional operation without external matching. Its 1-bit architecture uses a single D0 control line to toggle between 0 dB (insertion loss state) and 16 dB attenuation states, with glitch-free switching ensured by internal bias sequencing.

It supports dual-supply (±3.3 V) operation for optimal linearity (P0.1dB = 33 dBm typ. in insertion loss state) or single-supply (VDD = 3.3 V, VSS = GND) for simplified system integration-though with trade-offs: P0.1dB drops to 21 dBm and RF settling time increases to 350 ns @ 0.1 dB under single-supply conditions.

Key Specifications

Pinout & Package

ADRF5714BCCZN-R7 is housed in a RoHS-compliant, 12-terminal, 2.25 mm × 2.25 mm land grid array (LGA) package (package code CC-12-6) with an exposed thermal pad (EPAD) requiring connection to PCB ground for RF and thermal performance. Thermal resistance θJC = 50°C/W enables reliable operation at +105°C case temperature.

FAQ

What is the maximum RF input power the ADRF5714BCCZN-R7 can handle continuously?

The ADRF5714BCCZN-R7 supports 30 dBm steady-state average RF input power at TCASE = 85°C under dual-supply operation (±3.3 V). At +105°C case temperature, this derates by 3 dB to 27 dBm average. Peak power handling remains 33 dBm under both conditions, provided thermal design meets θJC = 50°C/W via proper EPAD grounding and via count.

Does the ADRF5714BCCZN-R7 require external DC blocking capacitors on ATTIN or ATTOUT?

No, the ADRF5714BCCZN-R7 features DC-coupled RF ports: ATTIN and ATTOUT are internally biased to 0 V DC, so no external DC blocking capacitors are required when the connected RF line operates at 0 V DC potential. This simplifies layout and preserves broadband impedance match from 100 MHz to 30 GHz.

Can the ADRF5714BCCZN-R7 operate from a single 3.3 V supply?

Yes, the ADRF5714BCCZN-R7 supports single-supply operation with VDD = 3.3 V and VSS tied to ground. However, this configuration reduces P0.1dB to 21 dBm (vs. 33 dBm dual supply) and increases RF amplitude settling time to 350 ns @ 0.1 dB (vs. 110 ns), as documented in Table 2 of the datasheet.

What is the recommended PCB layout for optimal RF and thermal performance of the ADRF5714BCCZN-R7?

Use coplanar waveguide (CPWG) with 16 mil trace width and 6 mil ground clearance for 50 Ω impedance. Connect all GND pins and the EPAD to a solid ground plane using ≥8 thermal vias. Place 100 pF bypass capacitors on VDD and VSS close to the package. Route D0 with controlled impedance and minimize stub length to preserve signal integrity.

Is the ADRF5714BCCZN-R7 pin-compatible with other devices in the ADRF57xx family?

No, the ADRF5714BCCZN-R7 is not pin-compatible with other ADRF57xx variants (e.g., ADRF5720, ADRF5730). It uses a unique 12-terminal LGA (CC-12-6) footprint with dedicated ATTIN, ATTOUT, VDD, VSS, D0, and multi-GND arrangement. Pin mapping and supply requirements differ across the family, requiring separate layout for each part.
