Us Patents

Adaptive Receiver Linearity Techniques For A Radio Transceiver

US Patent:
6298221, Oct 2, 2001
Filed:
Apr 1, 1998
Appl. No.:
9/053842
Inventors:
Dien M. Nguyen - Encinitas CA
Assignee:
Denso Corporation - Kariya
International Classification:
H04B 138
H04B 110
H04B 106
US Classification:
455 73
Abstract:
Characteristic of the transceiver is altered when intermodulation distortion is detected. This can increase bias to the LNA or reduce the signal to the LNA.

Temperature Compensated Wide Dynamic Range Power Detection Circuitry For Portable Rf Transmission Terminals

US Patent:
5796309, Aug 18, 1998
Filed:
Jul 2, 1996
Appl. No.:
8/677333
Inventors:
Dien M. Nguyen - Carlsbad CA
Assignee:
Nippondenso Co., Ltd. - Kariya
International Classification:
H03F 130
H03G 320
US Classification:
330289
Abstract:
A detector for a portable telephone or the like samples RF transmit power, detects the sampled signal using a Schottky diode and uses a logarithmic amplifier to apply a compressive function to the post-detection signal. The compressive function emphasizes power level changes at the low end of the transmission spectrum and de-emphasizes power level changes at the high end of the transmission spectrum. In this way, the range of detected powers required to be processed by subsequent circuitry is reduced, thereby simplifying the design of the circuit. To improve stability of the detector with respect to temperature fluctuations, the semiconductor element in the amplifier which provides its logarithmic characteristics is temperature-compensated, as is the detector diode.
