design of frequency switchable dual-band branch-line coupler.
Frequency switching is achieved by increasing the power of the
laser applied to the highly resistive silicon wafer and changing
the properties of silicon under optical illumination. The
advantages of this approach are high-speed switching,
electromagnetic transparency (no interference) and thermal and
electrical isolation between the coupler and the control circuit. A
frequency shift of 35% and 10% has been achieved from all
switches off to all switches on in lower (900 MHz) and upper
(1800 MHz) frequency bands, respectively.
