  • Patent number: 7096025
    Abstract: A communication device (105,200) includes a cordless telephone (205) and a two way radio (210). The communication device (105,200) is adapted to place an active cordless telephone call in a low frequency mode in response to receiving an incoming two way radio communication. The communication device (105,200) is adapted to then establish communication within the two way radio communication. The communication device (105,200) periodically re-establishes the cordless telephone call to maintain communication with a cordless base station (120) until the two way radio communication is completed.

  • Patent number: 6229097
    Abstract: A substrate 15 has an electrically adjustable trim pad 50 on the bottom side. A circuit pattern 18 resides on the top side, covered by an RF shield 20. The trim pad is located on the bottom side directly below the RF shield, and is electrically connected 52 to the circuit pattern. A number of surface mount connections 30, typically C5 solder bumps, are located on the bottom side, and surround the trim pad. The trim pad is trimmed after the RF shield is attached, thus providing more accurate tuning of the circuit on the top side.

  • Patent number: 6188287
    Abstract: 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.

  • Patent number: 6055421
    Abstract: A radio receiver operates primarily in a first operating mode to process received signals (410). When a carrier signal detect is triggered while in the first operating mode (415, 420), the receiver temporarily operates in a second operating mode which has receiver parameters selected to reduce carrier detect falsing when compared to the first operating mode (430). Preferably, in the second operating mode, the receiver's frequency and time response characteristics are modified to facilitate carrier squelch detection. Carrier squelch is performed if a carrier signal detect is triggered while the receiver operates in the second operating mode (440, 450, 460, 470).

  • Patent number: 6023198
    Abstract: 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.

  • Patent number: 5654676
    Abstract: A voltage controlled oscillator module (100) (400) provides tuning capability for the VCO in a shielded environment. The module includes a trimmable capacitor (110) (410) having metal plates (112, 114), (412, 414, 416) capacitively coupled through the substrate. One of the metal plates (114) (416) is a trimmable plate which can be trimmed to tune the VCO frequency. The trimmable metal plate (114) (416) remains exposed on the bottom surface (108) (408) of the substrate (104) (404) so that the frequency of the VCO can be tuned while the reminder of the oscillator circuitry (102) (402) on the top surface (106) (406) is encapsulated by a ground shield (116) (418).

  • Patent number: 5650755
    Abstract: A voltage controlled oscillator module assembly (300) minimizes microphonics in a low profile package. Included within the module (300) are a substrate (302), VCO circuitry (308), and a ground shield (314) encapsulating the VCO circuitry. Included within the VCO circuitry (308) is at least one resonator (310) which is solderable on at least two of its surfaces. One surface of the resonator (310) is soldered to the substrate (302) while another surface of the resonator is soldered to the shield (314). An improved ground is thus provided to the resonator (310) which reduces the occurrences of microphonics while providing a low profile package for the module (300).

  • Patent number: 5621362
    Abstract: An oscillator (100) includes a tank circuit (102) coupled to a an active circuit (108). The feedback (104) provides the necessary feedback between the tank and the active circuit necessary for oscillation. The active circuit (108) is biased via a biasing circuit (106) and coupled out to a load via an external coupling (110). The active circuit (108) includes two transistors (124, 126) coupled to each other in a cascode configuration. Transistor (126) provides the collector current for transistor (124) while preventing it from entering saturation prematurely. The biasing circuit (106) provides sufficient current drain for the transistor (126) in order to provide for optimum phase noise and bandwidth performance of the oscillator 100.

  • Patent number: 5512862
    Abstract: An oscillator (200) with improved sideband noise is disclosed. This improvement is accomplished without affecting the Q or the output power of the oscillator (200). The improvement is realized by increasing the rate of change of reactance over frequency. The increase in the rate of change is realized by placing two transmission lines (208, 210) in close proximity of each other. This increase assures oscillation while minimizing the sideband noise, and providing maximum bandwidth.
