摘要： A receiver (100) provides dual band features by providing two signal paths (106, 108) off an antenna (102), one for UHF operation (106) and one for VHF operation (108). The two signals paths (106, 108) feed into a single broadband input (124) of a direct conversion receiver (114). The UHF path (106) utilizes UHF front end circuitry (110) while the VHF path (108) is implemented with a loading/isolator circuit (120) and a matching circuit (122). The loading/isolator circuit (120) loads the antenna (102) and isolates UHF signals while the matching circuit (122) provides a match between the loading isolator circuit (120) and the direct conversion recover (114). Selectable matching circuitry (126, 128) and selectable VCO circuitry (132, 134) configures the direct conversion receiver for the UHF or VHF mode of operation.

摘要： A receiver (600) uses a scanning technique (100) to minimize scan time. An initial bandwidth setting is selected that covers multiple channel frequencies (106). A signal detection step (108) is performed looking for channel activity. As channel activity is detected, the bandwidth of a baseband filter (628) is narrowed (140, 146). The radio remains programmed to the same channel while the bandwidth is varied. Once the last signal detection with the narrowest possible bandwidth setting has been determined (144, 150, 152) the radio is programmed to that channel. Thus, more than one channel frequency is capable of being scanned without reprogramming the radio to a new channel for each scan.

摘要： A phase noise optimization circuit (208) minimizes phase noise for a voltage controlled oscillator (VCO) (202). Control circuitry (214) locates a minimum phase noise region for VCO operation based on the slope of the VCO's changing control voltage (206) versus changing bias voltage (204) for a bias voltage range. The control circuitry (214) then adjusts the bias input so that the VCO operates in a region of minimum phase noise.

摘要： A self-tuning VCO (116) receives a control voltage input (Vcont) (114) and an adjustable programmable voltage (Vadj) (122) and provides optimized locked conditions even under variations in temperature. A radio temperature is measured and stored (204) while Vadj (122) is initialized and stepped and Vcont (114) attempts to lock the VCO on frequency. Once a locked condition is achieved, the Vcont (114) is monitored to determine if it falls within a predetermined voltage range. If a non-optimized condition is detected, then the Vadj (122) is automatically adjusted until the VCO (116) becomes locked with a Vcont which falls within the predetermined voltage range. When a locked condition is achieved, the radio temperature is monitored and compared (212) to the original stored temperature (204). If a temperature threshold limit is reached (216) then the VCO is re-checks itself for a locked condition and re-optimizes itself to accommodate for the variations in temperature.
