Abstract: A zero Intermediate Frequency (IF) transmitter and receiver are implemented within a transceiver to eliminate interference in the receive band. An outpu t of a tunable high oscillator to generate a frequency source that is an integ er multiple of the desired transmit LO frequency. The frequency source is coupl ed to an amplitude limiter and frequency divider. The output of the frequency divider is used as the transmit LO to directly upconvert baseband signals to the desired output frequency without the need for an IF stage. Direct upconversion of the baseband transmit signals without an IF stage eliminates spurious frequency products that are produced in the receive band.

Abstract: A portable phone has an internal battery and an external battery pack is releasably attachable to the phone. A control unit in the phone controls connection of the respective batteries to a phone power input, depending on the detection of the external battery voltage. Whenever an external battery is present with a voltage above a predetermined minimum value, the external battery will be connected to the phone power input to provide power to operate the phone, so that the internal battery lifetime is extended. When the external battery voltage falls below the minimum value, or the external battery is removed, the unit automatically switches to internal battery power, so that the external battery can be changed without interrupting power supply to the phone, if the phone is on or during a call.

Abstract: A portable phone has an outer casing with opposite upper and lower walls, one of the walls having an opening for access to the interior of the casing, and a lid removably mounted in the opening for normally closing the opening. A main circuit board is mounted in the outer casing, with a plurality of phone components mounted on the circuit board. A predetermined region of the board aligned with the opening is left exposed or empty of components, and forms a recess for receiving a battery. The battery receiving recess has contact pads, and a battery is removably engaged in the recess with battery contacts engaging the contact pads in the recess, whereby the battery can be removed and replaced via the opening after opening the lid.

When the external battery voltage falls below the minimum value, or the external battery is removed, the unit automatically switches to internal battery power, so that the external battery can be changed without interrupting power supply to the phone, if the phone is on or during a call. An improved multi-phase software controlled battery-charging method and apparatus is used to charge the internal and external battery packs. The preferred battery-charging method uses a multi-phased charging approach comprising a trickle-charging phase, a fast-charging phase, and a top-off charging phase. The internal battery is charged to near-full capacity by trickle-charging (when required) and subsequently fast-charging the battery. The external battery is similarly charged to near-full capacity. Thus, both batteries are charged to near-full capacity in a substantially reduced charging time period as compared with the total charging time.

Abstract: A battery protection circuit for an external battery pack has a switch for controlling connection of a battery output to a load and a detector for detecting a resistance at a load output terminal. A first comparator compares the detected resistance to a predetermined maximum value, and a second comparator compares the detected resistance to a predetermined minimum value. If the detected resistance is in the range between the minimum and maximum values, a control signal is produced to enable connection of the battery output to the load. If the detected resistance is outside the range, the switch is disabled and no current can flow to the load.
