  • Multi-mode transmitter for transmitter for signals having varying deviation levels
    Patent number: 5590402
    Abstract: A dual-mode transmitter (100) adjusts a signal's deviation level when switched between a wideband mode and a narrowband mode of operation. The transmitter (100) automatically attenuates the deviation of the signal based on a ratio of the maximum deviation level for the wideband mode to the maximum deviation for the narrowband mode utilizing wideband/narrowband maximum deviation adjust circuitry (115). Because the attenuation based on the ratio of the maximum deviation levels is too large for a narrowband mode signal having average deviation, the signal is amplified based on a ratio of the average deviation level for the wideband mode to the average deviation for the narrowband mode utilizing wideband/narrowband average deviation adjust circuitry (103). Attenuation and amplification of the signal's deviation occur when the dual-mode transmitter (100) is operating in the narrowband mode.
