Pocket transceiver
First Claim
1. A portable transceiver apparatus comprising:
- a transceiver body including means for transmitting and receiving communication signals, input means for supplying communication signals to be transmitted, output means for outputting received communication signals, and internal power supply means for supplying power to said means for transmitting and receiving, and said input and output means, said means for transmitting and receiving communication signals including a control portion outputting communication signals at a level fixed to a specified lowest output level out of a plurality of levels, a transmitter filter connected with the control portion directly by separable connection terminals, and a receiver filter connected with the control portion directly via other separable connection terminals; and
an adapter to be detachably connected to said transceiver body, including amplifying means for amplifying signals to be transmitted from said control portion through said terminals which are detached from the transmitter and receiver filters when the adapter is connected to said portable transceiver body, control means responsive to a control signal from said control portion for setting the gain of said amplifying means to one level out of a plurality of levels, means for coupling signals from said amplifying means to an external antenna, and means for coupling signals from said external antenna to said means for transmitting and receiving.

Abstract
A pocket transceiver can be, for example a portable wireless telephone apparatus small enough to be put into a pocket of a user. The apparatus operates at a low power level. The pocket transceiver as an independent unit only handles signals at a low power level and is suitable for communication over close range. The pocket transceiver can also be used as a telephone apparatus for communication over long range, such as a mobile transceiver in a vehicle, by being connected to an adapter, which includes a power amplifier and a power controller for selecting an output power level out of multiple levels in response to an instruction from a transmitting-receiving unit of the pocket transceiver.
