摘要： A full duplex radio (10) having improved properties is obtained by using asymmetric surface acoustic wave (SAW) filters (70, 92, 100, 100', 112). The filters (70, 92, 100, 100', 112) are composed of series (50 1 , 50 1 ') and parallel (50 2 , 50 2 ') coupled SAW resonators. Asymmetry is obtained by covering either of the series (50 1 , 50 1 ') or parallel (50 2 , 50 2 ') resonators of each filter (70, 92, 100, 100', 112) with a dielectric layer (96) to increase the SAW coupling coefficient (Cs, Cp) of the covered resonators (50 1 ', 50 2 ') relative to the uncovered resonators (50 1 , 50 2 ). The filters (70, 92, 100, 100', 112) are desirably in pairs arranged with mirror image frequency asymmetry such that the steeper skirts (87, 79) of the frequency response (91', 91'') are adjacent. Greater pass-band bandwidths (77, 77', 77'') can be obtained without adverse affect on transmitter and receiver isolation.
摘要翻译：通过使用不对称表面声波（SAW）滤波器（70,92,100,100'，112）获得具有改进性能的全双工无线电装置（10）。滤波器（70,92,100,100'，112）由串联（501,501'）和平行（502,502'）耦合的SAW谐振器组成。通过用介电层（96）覆盖每个滤波器（70,92,100,100'，112）的系列（501,501'）或平行（502,502'）谐振器中的任一个来获得不对称性以增加SAW 所覆盖的谐振器（501'，502'）相对于未覆盖的谐振器（501,502）的耦合系数（Cs，Cp）。滤波器（70,92,100,100'，112）理想地成对布置为镜像频率不对称，使得频率响应（91'，91“）的较陡的裙部（87,79）相邻。可以获得更大的通带带宽（77,77'，77“），而不会对发射机和接收机的隔离产生不利影响。

摘要： A method for making an acoustic wave device (500, 600, 701, 801, 901, 1001), and an acoustic wave device (500, 600, 701, 801, 901, 1001) made by the method. The method comprises steps of providing a substrate (11) capable of supporting acoustic wave propagation and disposing a first transducer (518, 518') thereon. Disposing the first transducer (518, 518') includes disposing first through fourth electrode groups on the substrate. The first group (514') couples to a first electrical interconnection (17+). The second group (514'') couples to a second electrical interconnection (17-). The third group (519) couples to a common electrical interconnection (17') and is interleaved with the first group (514') of electrodes. The fourth group (520) couples to the common electrical interconnection (17') and is interleaved with the second group (514''). The fourth group (520) is disposed in an in-line configuration with the third group (519) and is offset therefrom by an integral number of half-wavelengths of an acoustic wave corresponding to a center frequency of the acoustic wave device (500, 600, 701, 801, 901, 1001).

For a centerline (67 or 77)-to-centerline (67 or 77) distance of a first adjacent pair of transducers (46, 42, 42', 47, 47', 43, 43', 48, 48', 44, 44', 49, 49') D₁, and centerline (67 or 77)-to-centerline (67 or 77) distances of other adjacent pairs of transducers (46, 42, 42', 47, 47', 43, 43', 48, 48', 44, 44', 49, 49') D₂ to D T-1 , then at least some of D₂ to D T-1 differ from D₁ by a non-integral number of wavelengths.
