The Balun Ember Transformer strip is a set of five signal-conditioning transformers from Wurth Elektronik. This product is designed to convert an unbalanced signal in a transmission line into a balanced one and vice versa. Each transformer operates within a frequency range of 2400MHz to 2500MHz and offers an impedance of 50 ohms unbalanced and 100 ohms balanced.Originally, these transformers were utilized in the ATmega128RFA1 Development Board. However, they are no longer required for that purpose, hence their availability at a significantly reduced price. This product is ideal for anyone who could find a use for one or more of these versatile integrated circuits.Please note, this product is categorized under “Ding & Dent”. This means that once the current stock is depleted, it will not be replenished. So, grab them while stocks last!For more detailed information about the product, please refer to the datasheet available on the Sparkfun website. https://elecena.pl/product/27748418/sparkfun-balun-ember-transformer-strip-of-5 2025-01-23 https://elecena.pl/product/27748418/sparkfun-balun-ember-transformer-strip-of-5 2026-04-12
