摘要： To secure the benefits of a low phase noise, wide tune range SAW (Surface Acoustic Wave) oscillator in noisy environments, a tunable two port SAW resonator circuit (102) is employed within the oscillator in differential mode, connected to a differential amplifier circuit (110) to create a differential oscillator (100). In the absence of any need for ground or power supply voltage level references, low phase noise/edge jitter is maintained even in hostile environments while providing sufficient tune range to track small frequency changes. The resulting differential mode SAW oscillator is thus well-suited for use, for instance, in clock recovery within SONET applications.

摘要： A two port, single pole SAW resonator (200) is employed for a local oscillator (100) to eliminate the secondary frequency responses of the prior art without adding additional inductances and capacitances within an amplifier stage (101). The stray capacitance (C 01 ,C 02 ) which is seen within the equivalent circuit of the single pole, two port SAW resonator (200) at a port (201,202) for the SAW resonator is tuned out by coupling an appropriately sized inductance (L 01 ,L 02 ) in parallel with the stray capacitance (C 01 ,C 02 ). Access to the series resonator (L M , C M ,R M ) within the SAW resonator equivalent circuit (200) is thus provided, permitting direct tuning of the resonant frequency for the SAW resonator. The high Q of the SAW resonator (200) ensures low phase noise/edge jitter, while direct tuning of the series resonator enables a wide tune range. The tunable SAW resonator circuit (102) is thus well-suited for use in a low phase noise tunable oscillator employed, for instance, in clock recovery within SONET applications.
摘要翻译：本体振荡器（100）采用双端口单极SAW谐振器（200），以消除现有技术的次级频率响应，而不会在放大器级（101）内增加额外的电感和电容。在用于SAW谐振器的端口（201,202）处的单极两端SAW谐振器（200）的等效电路内观察到的寄生电容（C01，C02）通过耦合适当尺寸的电感（L01，L02 ）与杂散电容（C01，C02）并联。因此提供了在SAW谐振器等效电路（200）内的串联谐振器（LM，CM，RM）的访问，允许对SAW谐振器的谐振频率进行直接调谐。 SAW谐振器（200）的高Q确保了低相位噪声/边缘抖动，而串联谐振器的直接调谐可实现较宽的调谐范围。因此，可调谐SAW谐振器电路（102）非常适合用于例如在SONET应用中的时钟恢复中使用的低相位噪声可调谐振荡器。

摘要： In a radio transmitter, an amplifier, a resonator and an antenna together form an oscillation loop. The oscillating energy of the oscillation loop is efficiently emitted from the antenna as a radio wave. Most of the oscillation power of the oscillation loop is supplied to the radiation resistance of the antenna because the transmitter has no components outside the loop which may consume the oscillation power.

摘要： A crystal-controlled oscillator circuit is modified by the present invention by replacing the crystal with the first signal port of a two-port SAW resonator filter that has a low-loss primarily inductive characteristic and taking the oscillation output from the other port of the filter to provide an oscillator frequency with harmonics that are reduced significantly when compared to the output of a crystal-controlled oscillator.

摘要： A circuit for generating a succession of fast rising voltage pulses comprises an inductor (L2) connected between first and second circuit nodes (A, B), a step recovery diode (D) connected between a reference potential level and the first circuit node, and a current switch (Q4, Q5) having a first state in which it conducts current in one direction with respect to the second circuit node and a second state in which it conducts current in the opposite direction with respect to the second circuit node. An oscillator (Q1, Q2, SR) is connected to the current switch for alternately and repeatedly placing the current switch in its first state and its second state. Preferably, the oscillator comprises a SAW resonator (SR) having a high Q and a parallel LC tank circuit (L1, C1) having a low Q, connected in a closed positive feedback loop.
