Tagore Technology Inc., a pioneer of high-power GaN-based RF switches, announced the introduction of the TS8728N and TS8729N asymmetrical reflective single-pole two throw (SPDT) switches designed for broadband, high-power switching applications. The new feature-rich switches offer best-in-class insertion loss, power handling, high linearity and high isolation performance and are well-suited for L- and S-Band radar and cellular infrastructure applications. The TS8728N is designed to operate at 400 W of pulse power with 2 ms pulse width and 20 percent duty cycle in S band whereas TS8729N is designed to operate at 550 W of pulse power with 2 ms pulse width and 20 percent duty cycle. Th devices operate with a single +5 V supply and switch with a single control voltage (0 to 3 V). They can be tuned to specific RF bands within the range of 0.3 to 5.0 GHz by modifying select external SMT components.
These new devices are compact, integrated high-power single-pole, double-throw (SPDT) with on board driver circuits. TS8729N can cover 500 MHz to 2.0 GHz and provide very high RF power handling & high linearity within a small package size. The TS8728N covers 0.5 to 5.0 GHz and has been optimized for switching speed.
