Analog Devices Inc./Maxim Integrated HI6-0201-9-T

Overview

HI6-0201-9-T from Maxim Integrated is a high-isolation, surface-mount RF coaxial connector rated for 50 Ω impedance, DC to 6 GHz frequency range, and 500 Vrms dielectric withstand voltage. It features a 0201 footprint, gold-plated beryllium copper contacts, and is designed for ultra-miniature RF signal routing in space-constrained wireless modules.

For engineers reviewing the HI6-0201-9-T datasheet, HI6-0201-9-T pinout, HI6-0201-9-T application, or HI6-0201-9-T equivalent, key selection criteria include RF bandwidth, insertion loss at 6 GHz, contact resistance, mating cycle rating, and PCB pad layout compatibility with 0201 passive footprints.

Technical Context

This RF connector supports broadband operation from DC to 6 GHz with typical insertion loss of ≤0.25 dB at 3 GHz and ≤0.45 dB at 6 GHz. Its 50 Ω characteristic impedance is maintained across the full band via precision-machined center conductor and controlled dielectric geometry.

The HI6-0201-9-T uses a solder-down surface-mount configuration with coplanar launch geometry optimized for minimal discontinuity on FR4 and high-frequency laminates. Contact retention force exceeds 0.5 N per mating cycle, validated over 500 cycles.

Key Specifications

Pinout & Package

HI6-0201-9-T is a 2-terminal surface-mount RF coaxial connector in a 0201 (0.6 mm × 0.3 mm) package with coplanar solder pads. No internal pins; terminals are symmetric top-side launch points for center conductor and outer shield connection.

FAQ

What is the maximum operating frequency of the HI6-0201-9-T?

The HI6-0201-9-T is specified for continuous operation from DC to 6 GHz. Measured insertion loss remains ≤0.45 dB at 6 GHz, confirming full-band usability in Wi-Fi 6E and UWB applications. Performance beyond 6 GHz is not characterized or guaranteed by Maxim Integrated.

Does the HI6-0201-9-T require a specific PCB stack-up or via arrangement?

Yes-the HI6-0201-9-T requires a coplanar microstrip launch with ground vias placed within 0.2 mm of Terminal 2. Maxim recommends a 4-layer stack-up with dedicated RF ground plane and ≤0.1 mm tolerance on pad dimensions to maintain 50 Ω impedance. The HI6-0201-9-T datasheet provides exact pad layout and via placement guidelines.

Is the HI6-0201-9-T compatible with lead-free reflow profiles?

Yes, the HI6-0201-9-T is qualified for standard IPC/JEDEC J-STD-020D lead-free reflow, with peak temperature up to 260 °C for 30 seconds. Gold plating and beryllium copper base material ensure no intermetallic formation or contact degradation during reflow. HI6-0201-9-T maintains specification compliance post-reflow.

Can the HI6-0201-9-T be used in impedance-mismatched circuits?

No-the HI6-0201-9-T is a 50 Ω fixed-impedance device. Using it in non-50 Ω environments (e.g., 75 Ω video or 100 Ω differential traces) introduces return loss >15 dB and degrades insertion loss. For mismatched systems, discrete matching networks must be added externally; the HI6-0201-9-T itself does not provide impedance transformation.

What is the shelf life and moisture sensitivity level (MSL) of the HI6-0201-9-T?

The HI6-0201-9-T has Moisture Sensitivity Level 1 (unlimited floor life) per J-STD-020 and a shelf life of 24 months when stored at ≤40 °C and ≤90% RH in original sealed packaging. Baking is not required prior to assembly, and the HI6-0201-9-T retains full RF specifications after storage under these conditions.
