Introduction

This testing was performed in order to evaluate the high-frequency electrical performance

SuperFly connectors in differential signaling applications. This report outlines frequency domain

performance metrics such as insertion loss (IL), return loss (RL) and crosstalk, as well as time-

domain performance metrics including impedance and eye pattern.

Product Overview

Glenair Series 88 SuperFly cordsets are the new standard for high performance, ultraminiature

interconnection systems. These lightweight, ultra-flexible connectors and cables are ideally

suited for battlefield and other high-performance applications.

Test Configuration

PC tail receptacles (PN 880-032R) were assembled onto the PCB test fixture. Test cables were

created using SuperFly plugs (PN 880-001P) with contacts terminated directly to low-loss 90Ω

nominal 30AWG twisted pair cable. A more detailed description of the test setup can be found

on page 13.

Performance Summary

Insertion loss (IL) data has been divided by two to show the performance of a single mated pair

of contacts terminated to 6 inches of cable. Insertion loss due to the test fixture PCB has been

de-embedded.

Parameter Results

Insertion Loss – Nano Contacts -3dB @ 3.9 GHz

Electrical Bandwidth* 8Gbps

Insertion Loss –Micro Contacts -3dB @ 2.9 GHz


Insertion Loss – Size 23 Contacts -3dB @ 2.1GHz


* The connector system electrical bandwidth is based on the -3dB insertion loss point of a single

mated pair, rounded up to the nearest 0.5GHz to account for test system loss that could not be

de-embedded from the results. The frequency is then doubled to determine an approximate data

rate in gigabits per second (Gbps). For example, a connector with a -3 dB point of 2.1GHz would

have a speed rating of 5.0Gbps.

APPENDIX B – Test System Description

A test fixture printed circuit board was designed specifically for this analysis. All traces to SuperFly contact pairs were designed to a nominal 50Ω ± 5% single-ended impedance but used in pairs for a 100Ω differential impedance.

All tests were performed using the Agilent E5071C ENA network analyzer with option TDR. All frequency domain data (IL, RL, NEXT, FEXT) has a 2% smoothing filter applied within the network analyzer. Device under test (DUT) includes two mated connector pairs (PNs 880-032R and 880-001P) with 12 inches of low-loss 90Ω±10Ω cable.

Test fixture and test cables were connected to the Agilent E5071C ENA Network Analyzer via high-performance 50-ohm coaxial test cables with SMA connectors. The system configuration is shown in the block diagram below:

APPENDIX C – Data Acquisition Methods

Frequency Domain (S-Parameter) Procedures

To ensure precise and repeatable data acquisition, extreme care was taken in the test fixture

design along with the calibration and testing procedure. A full calibration from 300kHz to 20GHz

was performed prior to testing using the Agilent N4433A eCal module. After calibration, test leads

were connected to the test fixture and applicable data was observed and saved into a .csv file.

At the completion of testing the acquired data was loaded into a spreadsheet for analysis and

figure generation.

Figure 6: Network analyzer with eCal module

Time Domain Procedures

Historically, dedicated TDR equipment was necessary to analyze time-domain response of RF

systems. The Agilent 5071C used for this testing contains software package “option TDR” which

mathematically derives time-domain information from acquired frequency domain data (S-

parameters). Even with bandwidth-limited data and a finite number of sample points, option TDR

offers a very accurate TDR representation. This also allows for generation of simulated eye

patterns to determine jitter and skew performance in relation to high speed data transmission. In

this report, the relationship between risetime and bandwidth was determined by using Time X

Bandwidth = 0.446, an equation provided by Agilent for use with the 5071C.
