This article covers Superbat 2インチ Mini PCI.

Overview

The Superbat 2-Inch Mini PCI to SMA Female Low-Loss Coaxial Cable is a pigtail adapter designed to convert the U.fl (IPEX) antenna connector on Mini PCIe wireless cards to a standard SMA female interface. Sold as a 2-pack, this cable uses an ultra-thin 1.13mm coaxial wire, making it easy to route in tight spaces inside a PC case or router enclosure. With 50Ω impedance and support for frequencies from DC to 18GHz, it covers 2.4GHz and 5GHz WiFi bands as well as cellular and GPS applications. It's an affordable solution for DIY antenna upgrades or replacements.

Connectivity & Compatibility

This cable connects Mini PCIe cards with U.fl/IPEX connectors to SMA female bulkhead or antenna ports. Compatible Mini PCIe cards include Intel 6235AN, AC 3160, 7260, AR9462, AR5B22, and many others. The SMA female end accepts standard SMA male antennas commonly used in WiFi, Bluetooth, and IoT devices. The cable length is only 5cm (2 inches), with a total length of 6.7cm including connectors. The thin 1.13mm diameter allows flexible routing even in cramped spaces like laptop chassis or compact routers.

Product Info

Released around 2019, this product is widely available on Japan. The 2-pack typically costs around ¥2,500, making it an entry-level option for antenna conversion. Warranty is handled by Superbat; check the product page for details. The package includes two cables only—no antennas or mounting hardware. Market positioning is entry to mid-range, targeting DIY enthusiasts who need a simple, low-cost way to adapt Mini PCIe antenna connectors to SMA. Compared to longer pigtails or IPEX4 variants, this cable sticks to the common U.fl standard for broad compatibility.

Best Use Cases

PC builders wanting to relocate WiFi antennas outside the case: By converting the Mini PCIe card's antenna port to SMA, you can attach any standard SMA antenna. The short cable is ideal when the SMA bulkhead is mounted near the card. Users upgrading wireless modules in routers or NAS devices: If your device has a Mini PCIe slot, this pigtail lets you replace the internal antenna with an external SMA antenna for better signal. The thin cable fits easily in tight enclosures. * Hobbyists experimenting with antenna modifications: The low price and 2-pack make it easy to try out antenna upgrades without a big investment. Note that the 5cm cable is short; for longer runs, you'll need an extension cable.
