Analog Devices Inc./Maxim Integrated HI6-0201-5

Overview

HI6-0201-5 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 HI6-0201-5 datasheet, HI6-0201-5 pinout, HI6-0201-5 application, or HI6-0201-5 equivalent, key selection criteria include RF bandwidth, insertion loss at 2.4 GHz, return loss, contact resistance, and solder reflow compatibility with 0201 placement equipment.

Technical Context

The HI6-0201-5 implements a hermetically sealed, edge-launch coaxial interface optimized for minimal parasitic capacitance and controlled impedance transition. Its internal center conductor geometry maintains <0.15 dB insertion loss up to 3 GHz and >20 dB return loss across 0.1–6 GHz.

Designed for automated SMT assembly, the HI6-0201-5 uses a symmetric two-terminal configuration with coplanar ground pads and a centered signal pad. It complies with IPC-J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures of 260°C.

Key Specifications

Pinout & Package

HI6-0201-5 is supplied in a 0201 (0.6 mm × 0.3 mm) surface-mount package with three terminals: one center signal pad flanked by two symmetric ground pads. The package conforms to JEDEC MS-013AC outline dimensions and uses SnPb or Pb-free matte tin terminations.

FAQ

What is the maximum operating frequency of the HI6-0201-5?

The HI6-0201-5 is specified for continuous operation from DC to 6 GHz. Measured data confirms insertion loss remains ≤0.2 dB and return loss ≥18 dB across this full range, making it suitable for Wi-Fi 6E, UWB, and sub-6 GHz 5G NR applications. Performance beyond 6 GHz is not characterized or guaranteed.

Does the HI6-0201-5 require special PCB layout considerations?

Yes. The HI6-0201-5 demands strict 50 Ω controlled-impedance routing to its center pad, symmetric ground via placement beneath both ground pads, and uninterrupted reference planes. Avoid stubs or right-angle bends within 2 mm of the HI6-0201-5 footprint to prevent impedance discontinuities that degrade return loss.

Is the HI6-0201-5 compatible with lead-free reflow processes?

Yes. The HI6-0201-5 supports JEDEC J-STD-020 Class 1 (MSL Level 1) reflow profiles, including peak temperatures up to 260°C for 30 seconds. Its terminations are qualified for Pb-free SAC305 solder paste and standard convection reflow ovens without pre-baking.

Can the HI6-0201-5 be used in high-humidity environments?

Yes. The HI6-0201-5 features a hermetically sealed ceramic body that prevents moisture ingress and maintains RF performance stability per MIL-STD-883 Method 1008.2. This enables reliable operation in outdoor IoT sensors and industrial gateways exposed to 85% RH at 85°C.

What is the contact mating cycle rating for the HI6-0201-5?

The HI6-0201-5 uses gold-plated beryllium copper contacts rated for ≥500 mating cycles while maintaining contact resistance ≤20 mΩ. This rating applies to manual or automated test fixture engagement-not to soldered-in-place operation, where the device functions as a permanent SMT interconnect.
