Abstract :
Results obtained utilizing an optically activated RF switch in the 2-30-MHz range demonstrate the advantages in optically controlled high-power switches from HF to millimeter wave. Testing of a 0.25-mm-thick p-i-n device activated with 116-W peak optical power from a two-dimensional laser array in a 50-Ω system shows isolation between 20.8 and 49 dB, and an average insertion loss of 0.38 dB when measured between 2.5 and 30 MHz
