  • Low-loss and wide-band acoustic delay lines using x-cut and y-cut lithium niobate piezoelectric thin films
    Patent number: 11942920
    Abstract: A piezoelectric thin film (PTF) is located above a carrier substrate. The PTF may be X-cut LiNbO3 thin film adapted to propagate an acoustic wave in at least one of a first mode excited by an electric field oriented in a longitudinal direction along a length of the PTF or a second mode excited by the electric field oriented at least partially in a thickness direction of the PTF. A first interdigitated transducer (IDT) is disposed on a first end of the PTF. The first IDT is to convert a first electromagnetic signal, traveling in the longitudinal direction, into the acoustic wave. A second IDT is disposed on a second end of the PTF with a gap between the second IDT and the first IDT. The second IDT is to convert the acoustic wave into a second electromagnetic signal.

  • Method of receiving data packets
    Publication number: 20070195826
    Abstract: A method of receiving data packets. In the method of receiving data packets, a determination is made as to whether a received data packet is received out of an expected order. If the determining step determines a received packet is out of the expected order, a time period is calculated to wait for one or more missing data packets based at least in part on an expected time of receiving the one or more missing data packets.
