The EME168 Series 70CM / 23CM Band RX/TX bias tee Kit is suitable for powering either the Mini-Kits 70CM band EME221-70CM or 23CM Band EME221-23CM Pre-amplifiers via the coaxial cable. The design has been optimized to cover the complete 400MHz to 1500MHz frequency range for the lowest loss and return loss. The board is fitted with PTC protection to safeguard against any short circuits on the RF/DC output, and over voltage. Transceivers with an accessory connector usually have a positive voltage, or grounded logic TX output that can be easily connected to the Bias Tee to control the switching. The Bias Tee is designed to handle up to 500 Watts CW.
