Appl. No.:

9/007899

Inventors:

Xing Ping Lin - Commerce MI

Assignee:

TRW Inc. - Lyndhurst OH

International Classification:

H04Q 718

US Classification:

455323

Abstract:

A system (10) for remote convenience control of performance of a function includes a portable transmitter unit (14) and a receiver unit (18). In one embodiment, the system (10) is a remote convenience vehicle system. The transmitter unit (14) transmits a signal (16). The signal has a RF frequency at an unknown value within a range of values and conveys a message that contains a function request. Within the receiver unit (18) is superheterodyne circuitry (32) that has a mixer (44). The mixer (44) mixes a RF signal (42) coming from an antenna (28) and a reference frequency signal from a reference oscillator (46), and outputs an intermediate frequency signal (50) conveying the message. A bandpass filter (66) filters the intermediate frequency signal to pass a range of frequency values smaller than a known range of intermediate frequency values. Tuning control circuitry (70) automatically adjusting the bandpass range of the bandpass filter (66) to vary the bandpass range over the intermediate frequency range.

Assignee:

TRW Inc. - Lyndhurst OH

International Classification:

H04B 104

US Classification:

455114

Abstract:

A transmitter for use with a receiver responsive to a function request signal transmitted by said transmitter for performing a requested function. The transmitter includes a controller for providing a function command and an LC oscillator for providing the request signal at a fixed frequency in response to the command from the controller. The oscillator includes a semi-conductor having first, second, and third electrodes and a tank circuit including first, second, and third impedances. A surface acoustic wave resonator is connected from the first electrode to ground. A feedback capacitor is connected from the second electrode to said first electrode for reducing spurious frequency signals.
