摘要： An acoustic wave ladder filter (30) with lossy inductances (42) connected in parallel with resonators (40). Shunt sections (36,37) of the ladder filter (30) include impedance inverters having pass frequencies within the stopband of series resonators (33,34,35). The filter (30) additionally includes variable capacitors (44) connected in parallel with the inductances (42) to provide adjustment capabilities. The use of lossy inductances (42) actually increases effective coupling coefficient of the filter (30) and improves insertion loss thereby allowing improved design flexibility.

摘要： A single-block ceramic filter (102) is coupled to two antennas (142 and 144) for providing both antenna duplexing and antenna-switched diversity in a duplex radio transceiver (100). One antenna (142) is coupled by the filter (102) to a transmitter (132), and both antennas (142 and 144) are switchably coupled by the filter (102) to a receiver (130) by diversity control circuitry (101) in response to a diversity control signal (137). A microcomputer (134) in the transceiver (100) is coupled to the receiver (130) for monitoring the received signal strength (135). When the received signal strength (135) drops in level indicating that the signal being received on one of the antennas (142 or 144) has become degraded due to fading or other interference, the microcomputer (134) changes the binary state of the diversity control signal (137) for switching the receiver (130) to the other one of the antennas (142 or 144 ).

摘要： A ceramic filter employs a novel tuning process which avoids the necessity of etching or abrading plating on the surface of the filter. The tuning is provided by determining a selected frequency related characteristic of the dielectric making up the block portion of the ceramic filter. For example, the quarter wave length frequency of the block may be measured. Next, plating artwork is designed in accordance with the determined selected frequency related characteristic. The artwork is then used for selectively applying a conductive material to a surface of the block in order to shift the determined selected frequency related characteristic to a desired (specified) frequency characteristic. By appropriately designing the artwork based on the determined selected frequency related characteristic, no etching or abrading to the plating on the block is required.

摘要： A high Q multi-layer ceramic transmission line resonator (100) used for RF applications. The resonator (100) includes a plurality of strips (102) which are separated by a ceramic substrate (104). Each of the strips are interconnected using vias (110) passing through the ceramic substrate (104).

摘要： The simulcast communication system includes a transmitting station for transmitting a first signal at a given frequency and a same frequency repeater (SFR) having a receiver for receiving the first signal and a transmitter for retransmitting the received signal at the same given frequency. The SFR rebroadcasts the received signal with a time delay of T. The receiver of the SFR receives the retransmitted signal as a spillover signal. A mechanism is coupled to the transmitting station for generating a second signal which consists of the first signal delayed in time by T1 which is approximately equal to T. Another mechanism coupled to the SFR substantially cancels the spillover signal and the second signal since the second signal is in phase with the spillover signal. Thus, the signal retransmitted by the SFR differs in phase from the second signal transmitted by the transmitting station only by the propagation delay between the SFR and the transmitting station, whereby the likelihood that a mobile unit will experience simulcast distortion due to the reception of the second signal and the retransmitted signal can be minimized. This invention further contemplates that multiple SFR's may be employed wherein each SFR includes a mechanism for cancelling any other retransmitted signals by other SFR's as received at each SFR.
摘要翻译：联播通信系统包括用于以给定频率发送第一信号的发送站和具有用于接收第一信号的接收机的相同频率中继器（SFR）和用于以相同给定频率重发接收信号的发射机。 SFR以T的时间延迟重播广播接收到的信号。SFR的接收机接收重传的信号作为溢出信号。一种机制耦合到发射台，用于产生第二信号，该第二信号由时间延迟大约等于T的T1组成。另一种耦合到SFR的机制基本上消除了溢出信号和第二信号，因为第二信号与溢出信号同步。因此，由SFR重传的信号与发送站发送的第二信号的相位不同，SFR与发送站之间的传播延迟不同，因此移动单元将因接收到可以使第二信号和重发信号最小化。本发明进一步考虑可以采用多个SFR，其中每个SFR包括用于在每个SFR处接收到的其他SFR消除任何其他重发信号的机制。
