Qorvo TGS2353-2 EVB

Overview

TGS2353-2 EVB from Qorvo is an evaluation board designed to characterize and validate the TGS2353-2 GaN-on-SiC high-power SPDT RF switch, operating from 0.5–18 GHz with ≤1.5 dB insertion loss, 30 dB typical isolation, and ±40 V control voltage capability in a 1.12 mm × 1.62 mm die format.

For engineers reviewing the TGS2353-2 datasheet, pinout, applications, or equivalent options, this EVB enables rapid RF performance validation-including switching speed (<35 ns), power handling (up to 10 W CW), return loss (>15 dB on-state), and thermal behavior-under real-world bias and signal conditions using calibrated microstrip interfaces.

Technical Context

The TGS2353-2 EVB implements a fully assembled, impedance-matched Rogers RO4350B PCB (ε_r = 3.48) with optimized Southwest Microwave 1092-02A-5 end-launch connectors, supporting direct RF characterization of the bare-die TGS2353-2 across its full 0.5–18 GHz band without external matching networks.

It supports dual-bias configuration (VC1/VC2 applied via pads 3/6 and 2/7 respectively), accommodates both SPDT and SPST operation (via 50 Ω termination), and maintains thermal integrity through AuSn-soldered mounting on a Cu-Mo carrier-enabling accurate measurement of channel temperature (158 °C) and junction-to-case thermal resistance (19.78 °C/W) under 10 W input power.

FAQ

What is the primary purpose of the TGS2353-2 EVB?

The TGS2353-2 EVB is a fully assembled evaluation board intended for laboratory characterization of the TGS2353-2 GaN SPDT switch. It enables engineers to measure insertion loss, isolation, return loss, switching speed, and thermal performance across 0.5–18 GHz without custom PCB development. The TGS2353-2 EVB uses industry-standard connectors and validated layout practices to ensure measurement fidelity and repeatability.

Does the TGS2353-2 EVB support both SPDT and SPST configurations?

Yes-the TGS2353-2 EVB supports both modes. In SPDT mode, RF In routes to either RF Out1 or RF Out2 based on VC1/VC2 polarity. For SPST use, one output port can be terminated with the onboard 50 Ω pad, allowing focused validation of a single path. This flexibility makes the TGS2353-2 EVB suitable for diverse RF architecture evaluations.

What RF connectors are used on the TGS2353-2 EVB?

The TGS2353-2 EVB uses Southwest Microwave model 1092-02A-5 end-launch SMA connectors, optimized for minimal discontinuity at the PCB edge. These connectors maintain 50 Ω impedance and support full-band operation up to 18 GHz, enabling accurate S-parameter measurements with vector network analyzers without adapter-induced errors.

How is thermal management handled on the TGS2353-2 EVB?

The TGS2353-2 EVB mounts the TGS2353-2 die onto a Cu-Mo carrier plate using AuSn solder, achieving a measured θ_JC of 19.78 °C/W. This design allows sustained 10 W CW operation while keeping channel temperature below 158 °C-critical for validating reliability in high-duty-cycle radar applications. The board includes no active cooling but supports heatsink integration via the carrier base.

Is the TGS2353-2 EVB RoHS compliant and ESD-safe?

Yes-the TGS2353-2 EVB complies with EU RoHS Directive 2011/65/EU (as amended), including lead-free, halogen-free, antimony-free, and PFOS-free construction. It handles the ESD-sensitive TGS2353-2 die per JS-001 HBM Class 1A requirements, and includes clear ESD handling guidance in its documentation to prevent gate oxide damage during lab use.
