Abstract: Ein Frontend-Modul zur Verwendung in einer drahtlosen Basisstation, wie einer Pikozelle, umfasst ein Gehäuse, das einen Hohlraum für einen Träger eingrenzt. Ein erster Abschnitt auf dem Träger definiert einen Signal-Sendepfad und umfasst wenigstens die folgenden diskreten elektronischen Komponenten: ein Bandpassfilter, einen Leistungsverstärker und einen Koppler. Ein zweiter Abschnitt auf dem Träger definiert einen Signal-Empfangspfad und umfasst wenigstens die folgenden diskreten elektronischen Komponenten: ein Bandpassfilter und einen Low-Noise-Verstärker. Ein Schalter auf dem Träger verbindet den ersten und den zweiten Abschnitt mit einem Antennenanschluss, und eine Wand in dem Gehäuse erstreckt sich durch einen Schlitz in dem Träger, um die Komponenten in dem ersten und dem zweiten Abschnitt zu trennen. Anschlüsse erstrecken sich durch eine Außenwand des Gehäuses und sind in Kontakt mit dem Träger.

Abstract: A frequency-adjustable oscillator suitable for digital signal clock synchronization comprises a SAW oscillator circuit for generating an analog controlled-frequency signal and a sinewave-to-logic level translator circuit in a double-sided package. The SAW oscillator circuit includes a tunable SAW resonator, a gain stage for energizing the SAW resonator, a voltage-variable control input for adjusting a frequency of the controlled-frequency signal, and a voltage-variable capacitive element operably linked to the SAW resonator and responsive to the control input. The sinewave-to-logic level translator circuit is operably linked to the SAW oscillator circuit and configured to generate a digital logic output signal having substantially the same frequency as the controlled-frequency output signal. The double-sided package includes a platform with sidewalls extending substantially upwardly to form a first cavity adapted to receive and electrically connect the SAW resonator and sidewalls extending substantially downwardly to form a second cavity adapted to receive and electrically connect at least one electronic component. A cover is coupled with the first cavity to create an isolated environment for containing the SAW resonator.

Abstract: A frequency-adjustable oscillator suitable for digital signal clock synchronization comprises a crystal oscillator circuit for generating a driving signal and having a voltage-variable control input for adjusting a frequency of the driving signal, a phase detector circuit for generating a phase offset signal, a filter which operates on the phase offset signal to produce a VCO control signal, a voltage controlled oscillator circuit operab ly linked to the filter and responsive to the VCO control signal for generating an analog controlled-frequency signal, a frequency divider circuit for generating a reduced frequency feedback signal in response to the controlled - frequency signal. The frequency-adjustable oscillator also includes a double - sided package including a platform having a central portion and an outer portion with sidewalls extending substantially upwardly and substantially downwardly from the outer portion of the platform. The upwardly extending sidewalls and the platform form a first cavity adapted to receive and electrically connect the quartz resonator. The downwardly extending sidewall s and the platform forming a second cavity adapted to receive and electrically connect at least one electronic component. A cover is coupled with the first cavity to create an isolated environmentfor containing the quartz resonator.
