Abstract
(A1) Die vorliegende Erfindung betrifft einen Hochfrequenzsender sowie ein Verfahren zu dessen Betrieb. Der Hochfrequenzsender (1) enthaelt: - einen Energiewandler (2) zur Energieversorgung des Hochfrequenzsenders, - eine mit einer Empfaengerschaltung verbundene Logikbaugruppe (3) zur Ablaufsteuerung des Hochfrequenzsenders sowie - eine Hochfrequenzsendestufe zur Funkkommunikation, wobei der Energiewandler (2) zumindest bereichsweise als Eingangselement zur Erzeugung von Eingangssignalen fuer die Empfaengerschaltung ausgebildet ist.

 

WO 2008031632 A1 UPAB: 20080417 NOVELTY - The transmitter (1) has an energy transducer (2) for supplying energy to the transmitter, and a logic component (3) that is connected to a receiver circuit for the executive sequencing of the transmitter. A high-frequency transmission stage is provided for radio communication, where the energy transducer is designed as an input unit for generating electric input signals for the receiver circuit. A data memory (4) is connected with the logic component, and a micro-antenna (6) for transmitting and/or receiving radio signals is connected with a radio transmission circuit (5). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating a high-frequency transmitter. USE - High-frequency transmitter for measuring an internal pressure of a tire of a motor vehicle. ADVANTAGE - The high-frequency transmitter can be operated as energy self-contained system even in long-term operation, works with high transmission power and can be designed in a compact manner.
