摘要： A method (100) for tuning a voltage controlled oscillator by changing electrical circuit parasitics includes a first step (102) of providing a voltage controlled oscillator circuit on a circuit board and a plurality of different metal lids each having different numbers, sizes and locations of holes. Each different lid presents a different electrical circuit parasitic to the voltage controlled oscillator. In a second step (104), the voltage controlled oscillator frequency is measured, and the frequency shift needed to achieve a desired operating frequency is calculated in a third step (106). In a fourth step (108), a lid is chosen that will present the parasitics needed to provide the amount of frequency shift needed. As a last step (110), the chosen lid is attaching to the circuit board to obtain the desired nominal operating frequency from the voltage controlled oscillator.

摘要： A front end module for use in a wireless base station such as a picocell includes a housing defining a cavity for a substrate. A first section on the substrate defines a signal transmit path and includes at least the following discrete electronic components: a bandpass filter, a power amplifier, and a coupler. A second section on the substrate defines a signal receive path and includes at least the following discrete electronic components: a bandpass filter and a low-noise amplifier. A switch on the substrate interconnects the first and second sections to an antenna terminal and a wall in the housing extends through a slot in the substrate to isolate the components in the first and second sections. Terminals extend through an exterior wall of the housing and into contact with the substrate.

摘要： A tuneable frequency translator is disclosed having electrical circuitry mounted to a circuit board. The circuitry is designed to provide a phase-locked loop with a resonator. Compliant material is positioned between the resonator and the circuit board. Operably coupled to the resonator is at least one passive device that is short-circuited by an electrically conductive lead. The resonant frequency of the frequency translator can be changed by severing the electrically conductive lead, and thus activating the associated passive device.

摘要： An oscillator assembly includes an oscillator circuit that is configured to generate a frequency signal. A temperature compensation circuit is in communication with the oscillator circuit and adapted to adjust the frequency signal in response to changes in temperature. The oscillator and temperature compensation circuits are located within an oven. A heater and a temperature sensor in communication with the heater are also both located in the oven. The temperature sensor is adapted to directly control the heater in response to changes in temperature. In one embodiment, the oscillator components are mounted to a ball grid array substrate which, in turn, is mounted on a printed circuit board. In this embodiment, a resonator overlies the ball grid array substrate and a lid covers and defines an oven and enclosure for the resonator and the ball grid array substrate. The oscillator and temperature compensation circuit are defined on the ball grid array substrate.

摘要： In a conventional quartz crystal resonator, a sacrificial quartz layer attached to the mounting posts and between the active, vibrating quartz layer and the package base reduces mechanical stresses on the active quartz layer caused by thermal expansion coefficient differences. The intermediate quartz layer is a sacrificial layer which acts to maintain the spacing of mounting posts.
