# Straight SMA Thru Hole RF Connector

**Type:** Product page · **SKU:** ADA4644 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/straight-sma-thru-hole-rf-connector.html ([markdown](https://core-electronics.com.au/straight-sma-thru-hole-rf-connector.html.md))

This is a great connector for anyone doing RF work, when a straight SMA connector is required. Solder it into your PCB for a very secure mechanical connection. You've probably seen tons of these on various development boards! The four mechanical connectors also act as the RF ground.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4644:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4644:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)
