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： 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： 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.

摘要： A pressure sensor that provides for multiple diaphragm sensing regions in a side by side configuration which can be formed into a stacked monolithic batch fabricated form. The multiple pressure sensor can be constructed to sense differential or absolute pressure as desired. In preferred forms of the invention, the pressure inlets are all on the same side of the monolithic structure to easily isolate the corrosive pressure media from the sensing means, which as shown comprise strain gage sensors on the sensing diaphragms as well as from the conductors carrying signals from the sensing means. The variable strain gage resistors on the sensor diaphragms are segregated from the media in several differet ways using isolating layers. The stacked sensor configuration insures that the device can be batched fabricated so that a number of sensors can be formed on chips that are stacked and bonded together, and then separated into individual sensors.

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.
