Latest Patents
Sakai's latest patents include a radio frequency switch and a wireless communication apparatus utilizing the same. The radio frequency switch features a first diode connected in series to a transmission port, with a low pass filter positioned between the first diode and an antenna port. Additionally, a second diode is connected between the reception port and the ground. This design incorporates a phase-shifting function that ensures the impedance seen from the first diode to the reception port is nearly open in the transmission band when current flows through the second diode. His second patent, the key opening apparatus, consists of an antenna that receives both a first signal of slower transmission speed and a second signal of higher transmission speed. This apparatus includes a receiving section, a filter, a comparator, and a decoder, along with another set of filter, comparator, and decoder. The receiving section processes the first and second signals in common, while the two decoders utilize a single microprocessor to output the results to an output terminal.
