MACOM Balun ETC1.5-4TR

The ETC1.5-4TR is a surface mount RF step-down auto-transformer with a 1.5:1 impedance ratio, designed for high-volume applications. It operates within a frequency range of 5 MHz to 1000 MHz and has an input impedance of 75Oc. The device features a maximum input power rating of 250 mW and can handle a DC current of up to 200 mA. The operating temperature range is from -40¬8C to +85¬8C. Insertion loss at 1000 MHz is specified at 0.78 dB, while the input return loss is greater than 20 dB across the specified frequency range. The product is available on tape and reel, with 2000 units per reel, making it suitable for automated assembly processes. The pin configuration includes primary and secondary connections, with specific pins designated for dot marking. This balun is a suitable choice for engineers looking for a reliable component for RF applications within the specified parameters.
