Check this product’s supported frequencies in the description/specs. - If you intend to operate outside shared/licence‑exempt conditions (e.g. in other bands, at higher power, with high‑gain antennas, or extended duty cycles), you must have the appropriate authorisation. **For use in other regions** - Follow the spectrum rules for your country/region and select frequencies and settings accordingly. A declaration of use will need to be submitted during checkout. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS114991131:1` (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/SS114991131:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description RF Explorer Upconverter is a high-performance RF frequency mixer to enable input frequency ranges from 100KHz to 250MHz in RF Explorer Spectrum Analyzer and other devices such as SDR and wideband radios. ![](https://core-electronics.com.au/media/wysiwyg/product_images/1509010715546994.jpg) RF Explorer Upconverter is a multi-purpose device: \* Includes an Upconverter Mixer to enable frequencies 100Khz - 250MHz in your RF Explorer Spectrum Analyzer or other devices such as RTL-SDR and converts into 530.1-780MHz \* Internal selectable Low Noise Amplifier of 25dB gain nominal, to increase the sensitivity of receivers, Spectrum Analyzers, Oscilloscopes and Near Field antennas in frequencies 100KHz - 4GHz \* Internal selectable Attenuator 30dB nominal to enable large-signal measurement ![](https://core-electronics.com.au/media/wysiwyg/product_images/RFEUDirectS11.jpg) - For more details about user guide and coding, please visit the Upconverter site here. - If you'd like to buy or change the RF Explorer Battery, please click here. **Features** - Internal LNA amplifier and selectable attenuator - In Mixer mode convert frequencies from input 100KHz-250MHz up to 530.1-780MHz output - In Bypass mode, it can work in frequencies from 50KHz to 4GHz including LNA and Attenuator - Compact size and lightweight - Solid aluminum metal case - The mini USB port is used for powering the unit DC 5V, easy connection to a PC, wall wart or even portable power bank battery. - Easy connection to RF Explorer with included RF adapter SNA Male-Male - Ideal device to amplify weak signals using RF Explorer Near Field antennas - CE / FCC / RoHS compliant **Technical details** - Dimensions 120mm x77mm x26mm - Weight G.W 95g - Battery Exclude - Input Frequency band Mixer Mode 0.1 – 250MHz - Input Frequency band: Bypass Mode 0 – 4GHz - LNA Frequency band 0 – 4GHz - Attenuator Frequency band 0 – 4GHz - Internal selectable LNA 25dB gain - Internal selectable Attenuator 30dB - Connectors Standard SMA 50 ohms RF connectors - Absolute Max input power Bypass and Attenuator mode +30dBm - Absolute Max input power LNA mode +5dBm - Mixer stability and accuracy (typical) +-10ppm ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/h/t/httpsstatics3.seeedstudio.comseeedfile2017-10bazaar604783_img_4438a.jpg)
