Analog Devices Inc. ADRF5130-EVALZ

Overview

ADRF5130-EVALZ from Analog Devices is an evaluation board designed to characterize and validate the ADRF5130 high-power silicon SPDT RF switch (0.7–3.8 GHz), supporting reflective 50 Ω operation, 46 dBm P0.1dB compression, and 0.6 dB insertion loss at 2 GHz in cellular infrastructure and test equipment applications.

For engineers reviewing the ADRF5130-EVALZ datasheet, ADRF5130-EVALZ pinout, ADRF5130-EVALZ application, or ADRF5130-EVALZ equivalent, this board enables rapid RF performance validation-including insertion loss, isolation, IP3, and thermal behavior-under real-world bias, control, and high-power CW/LTE signal conditions using SMA end-launch connectors and calibrated THRU path.

Technical Context

The ADRF5130-EVALZ implements a full-featured, eight-layer PCB platform with 2 oz copper top/bottom layers, Rogers RO4350 (10 mil) top dielectric for thermal stability, and FR-4 inner layers. It supports the ADRF5130's single 5 V supply, TTL-compatible VCTL control, and dc-coupled RF ports requiring external 100 pF blocking capacitors.

Board layout follows strict RF design rules: coplanar waveguide traces (18 mil width, 13 mil ground spacing), dense via stitching under the LFCSP exposed pad and RF paths, and dedicated bypass networks (100 pF / 1 nF / 1 µF) on VDD and VCTL. Thermal management includes provision for heatsink and mini DC fan mounting.

FAQ

What is the primary function of the ADRF5130-EVALZ?

The ADRF5130-EVALZ is a dedicated evaluation board for the ADRF5130 high-power SPDT RF switch. It provides a fully populated, RF-optimized platform with SMA connectors, calibrated THRU path, and thermal-aware layout to enable accurate measurement of insertion loss, isolation, IP3, and power-handling performance across 0.7–3.8 GHz under real operating conditions. The ADRF5130-EVALZ does not contain active circuitry beyond supporting the ADRF5130 device itself.

Does the ADRF5130-EVALZ include the ADRF5130 IC?

Yes, the ADRF5130-EVALZ includes one mounted ADRF5130BCPZ RF switch (U1) in its 24-lead 4 mm × 4 mm LFCSP package. The board is shipped fully assembled with all required bypass capacitors, dc-blocking capacitors, control resistors, and SMA connectors pre-soldered per Table 6 of the ADRF5130 datasheet Rev. C.

What RF connectors are used on the ADRF5130-EVALZ?

The ADRF5130-EVALZ uses three 2.9 mm end-launch SMA connectors (J1, J2, J3) for direct connection to RFC, RF1, and RF2 ports. These connectors maintain 50 Ω impedance match and support high-frequency operation up to 3.8 GHz. Each RF trace integrates a 100 pF dc-blocking capacitor between the connector and the ADRF5130 die.

How is thermal management implemented on the ADRF5130-EVALZ?

The ADRF5130-EVALZ employs multiple thermal strategies: dense via arrays under the ADRF5130's exposed pad and RF traces, 2 oz copper top/bottom layers, 10 mil thermally stable Rogers RO4350 top dielectric, and mechanical provisions for optional heatsink and mini DC fan mounting. This design sustains continuous-wave operation at ≥43 dBm input power with case temperature ≤85°C.

Is there a calibration path on the ADRF5130-EVALZ for S-parameter measurements?

Yes, the ADRF5130-EVALZ includes a dedicated THRU CAL transmission line that provides a direct, unswitched RF path between two SMA connectors. This path allows users to measure and de-embed the intrinsic board loss (including connector and trace contributions) when performing vector network analyzer (VNA) measurements of the ADRF5130 device itself.
