Analog Devices Inc. ADRF5347B2B-EVALZ

Overview

ADRF5347B2B-EVALZ from Analog Devices is an evaluation board designed to characterize and validate the ADRF5347 high-linearity silicon SP4T RF switch (1 GHz–6 GHz), supporting fast 720 ns 0.1 dB settling time, 84 dBm typical input IP3, and ±3.4 V/5 V dual-supply operation in a 4 mm × 4 mm LGA package. It enables rapid prototyping of 5G beamforming and antenna tilting architectures.

For engineers reviewing the ADRF5347B2B-EVALZ datasheet, ADRF5347B2B-EVALZ pinout, ADRF5347B2B-EVALZ application, or ADRF5347B2B-EVALZ equivalent, this board provides full RF path access to all five ports (RFC, RF1–RF4), integrated biasing, LVCMOS/LVTTL-compatible control interface, and optimized coplanar waveguide routing for accurate high-frequency measurement up to 6 GHz.

Technical Context

The ADRF5347B2B-EVALZ implements a fully populated, impedance-matched reference design for the ADRF5347 SP4T switch, featuring DC-coupled 50 Ω RF paths, on-board decoupling (100 pF + 4.7 μF per supply rail), and direct-access control lines (V1, V2, LS) with 1 kΩ series resistors. It supports both continuous-wave and LTE signal testing under thermal stress (up to +105°C case temperature).

Board-level timing alignment preserves the ADRF5347's 650 ns typical tON/tOFF and 720 ns 0.1 dB settling performance. The layout follows Analog Devices' CPWG stack-up recommendations (18 mil trace width, 13 mil clearance, 2.7 mil copper) on Rogers RO4350B substrate, with ground vias placed at ≤2 mm spacing for optimal RF return path and thermal conduction through the exposed pad.

FAQ

What is the primary function of the ADRF5347B2B-EVALZ?

The ADRF5347B2B-EVALZ is an evaluation board for the ADRF5347 SP4T RF switch. It provides full access to all five RF ports (RFC, RF1–RF4), dual-supply biasing (+5 V/−3.4 V), and LVCMOS/LVTTL control lines to enable lab-based validation of insertion loss, isolation, phase response, and power handling up to 6 GHz. The ADRF5347B2B-EVALZ does not contain active circuitry beyond passive support components.

Does the ADRF5347B2B-EVALZ support hot-switching validation at 105°C?

Yes - the ADRF5347B2B-EVALZ implements the thermal design guidelines from the ADRF5347 datasheet: exposed paddle soldered to dense thermal via array, ground plane coupling, and low-thermal-resistance Rogers RO4350B substrate. This allows sustained operation and measurement of the ADRF5347's 39 dBm CW and 49 dBm LTE peak power handling at TCASE = 105°C, as specified in Table 1 of the ADRF5347 datasheet Rev. A.

Can the ADRF5347B2B-EVALZ be used for back-to-back phase shifter testing?

Yes - the ADRF5347B2B-EVALZ supports the back-to-back configuration described in the ADRF5347 datasheet (Section "Back-to-Back Phase Shifter Reference Design"). Its independent RF port access, matched 50 Ω paths, and unobstructed control line routing allow direct cascading of two ADRF5347 devices to implement 4-step phase shifters (e.g., 0°/30°/60°/90° at 3.6 GHz), with measurement reference planes aligned to package boundaries.

What RF connector type is used on the ADRF5347B2B-EVALZ?

The ADRF5347B2B-EVALZ uses standard 50 Ω SMA female connectors for all five RF ports: one on RFC and one each on RF1, RF2, RF3, and RF4. These are DC-coupled and impedance-matched to the board's coplanar waveguide traces, enabling direct connection to vector network analyzers, signal generators, and spectrum analyzers without external adapters or matching networks.

Is the ADRF5347B2B-EVALZ RoHS-compliant and lead-free?

Yes - the ADRF5347B2B-EVALZ is manufactured to RoHS Directive 2011/65/EU and uses lead-free solder paste and finishes. Its PCB substrate (Rogers RO4350B), SMA connectors, and passive components comply with Analog Devices' environmental specifications, matching the RoHS status of the ADRF5347BCCZN device it evaluates.
