High-PERFORMANCE rf, mmwave and BRAODBAND TEST SOCKETs
At Signal Integrity, we design for the < -1dB insertion loss you budgeted for. From 5G to mmWave phased array antenna packages to highly dense 112G PAM4 PCIGen7 SerDes, our custom tuned RF test sockets deliver open eye and low VSWR signal transmission at the target Nyquist.
Tuned Impedance Broadband and RF Test INTERFACE CONFIGURATIONS
Achieving signal integrity past 60GHz requires more than just a high-speed probe—it demands a fully tuned interconnect environment. Our high bandwidth socket architectures utilize impedance-matched probes structures, tuned-dielectric housings (Engineered Cavity Tuned), and zero-stub contact designs to minimize insertion loss and resonances, control crosstalk and maintain smooth VSWR. Browse our primary RF and Broadband solutions below to find the ideal match for your 5G, SerDes, or Radar/Lidar test challenges.

Overview
KEY FEATURES OF OUR High Frequency TEST SOCKET ARCHITECTURE
- Zero-Stub Signal Path: Probe architecture eliminates resonance & inductive stubs internal in the probe path. This ensures flat insertion loss and minimal signal path resonance.
- Impedance Matched (42-55 Ω): We tune the cavity and probe solutions to match your DUT’s ideal IO impedance specifications. Socket signal paths maintain +/- 5% 50Ω (or 85Ω/100Ω differential) impedance from the PCB pad to the device lead.
- Advanced Materials: We utilize engineering plastics like Vespel® SP1 or PEEK450G to minimize dielectric loss (Dk and Df) and maintain stability under thermal stress.
- Hybrid Power Capability: Our impedance tuned socket probes can provide >4.5 amps continuous current using homogenous pins across the full grid array. Hybrid probe solutions can provide high-current solid plungers (up to 10A) in the same housing, allowing for complete SoC power testing without compromising RF performance.
- HFSS Simulation: Every high frequency socket design is simulated in Ansys HFSS™ prior to fabrication to guarantee S-Parameter performance and a design that will meet your performance and budget
VERIFIED PERFORMANCE & RAPID DELIVERY
HFSS™ Verified
We don’t guess. We simulate.
Every RF socket includes a full Ansys HFSS™ signal integrity report, validating insertion loss and return loss before we cut metal.
USA & Singapore Hubs
Global Engineering & Support
With HQ in Massachusetts and a fully equipped shop in Singapore, we bridge the gap between US design teams and Asian OSATs—providing local support in both time zones.
Reliable Delivery
Optimized Supply Chain
We manage logistics from both the US and Singapore to minimize shipping bottlenecks. Complex custom fixtures are typically deliverable to any global test floor in 6-7 weeks.
GET A FAST & ACCURATE QUOTE
To speed up your simulation and quote process, please have the following ready:
- Zero-Stub Signal Path: Number of high bandwidth device pads. Location of these pads on the part.
- Advanced Materials: Package dimensions, POD and pad interconnect type (BGA, LGA, other)
- Hybrid Power Capability: Do you need custom high-power solutions on your device (Kelvin, > 4 amps continuous current)
- HFSS Simulation: Do you need socket simulation to PCB layout support.
What is the typical insertion loss at 40 GHz?
Our coaxial sockets typically achieve better than -1dB insertion loss at 40 GHz. We provide a full S-Parameter simulation report for every custom design to verify performance against your budget.
Do you support PCIe Gen 6 and Gen 7?
Yes. Our 112G PAM4 and SerDes configurations are specifically designed for the tight return loss requirements of PCIe Gen 6 and emerging Gen 7 standards.
Can you match the footprint of my existing socket?
Yes. We specialize in “drop-in replacements” and can match the mounting footprint of legacy sockets from other vendors, often upgrading the performance without requiring a PCB respin.
