信号の強度が変化するような場合には、操作がきわめて
煩雑であった。In addition, some conventional transceivers can adjust the transmit power, but since they have to be adjusted manually, for example, when communicating while moving, the strength of the received signal may change. In cases where there is a change, the operation is extremely complicated.
本発明の目的は、上記従来技術の欠点を除き消費電力を
低減し、かつ、操作性の優れたトランシーバを提供する
ことＫある。SUMMARY OF THE INVENTION An object of the present invention is to provide a transceiver that eliminates the drawbacks of the prior art, reduces power consumption, and has excellent operability.
この目的を達成するため、本発明は、相手局からの受信
信号の強弱に応じて、送信回路の送信用力を自動的に調
節することによシ、消費電力の低減と操作性の向上とを
図った点に特徴がある。In order to achieve this object, the present invention reduces power consumption and improves operability by automatically adjusting the transmitting power of the transmitting circuit according to the strength of the received signal from the other station. It is distinctive in that it has been designed.

と受信の切換スイッチである。Embodiments of the present invention will be described below with reference to the drawings. The figure is a block diagram showing an embodiment of a transceiver according to the present invention, in which 1 is an antenna, 2 is a receiving circuit, 3 is a transmitting circuit, 4 is an automatic gain control circuit, 5 is an A/D converter, 6 is a block diagram showing an embodiment of a transceiver according to the present invention.
1 is a reset circuit, 7 is a memory circuit, 8 is a control circuit, 9 is a handset that serves both as a speaker and a microphone, and 10 is a transmission/reception switch.
同図において、切換スイッチ１０の操作によシトランシ

αとアンテナ１の接続端子Ｃとが接続されるとともに、
受信回路２の出力端子ｄと送受話器９の接続端子ｆとが
接続される。In the figure, when the transceiver is set to reception mode by operating the changeover switch 10, the input terminal α of the reception circuit 2 and the connection terminal C of the antenna 1 are connected, and
The output terminal d of the receiving circuit 2 and the connection terminal f of the handset 9 are connected.
したがって、相手局からの受信信号は、アンテナ１で受
信され受信回路２によシ所定の信号再生処理がなされた
後送受話器９に供給される。Therefore, a received signal from a partner station is received by the antenna 1, subjected to a predetermined signal reproduction process by the receiving circuit 2, and then supplied to the handset 9.
更に、上記の切換スイッチ１０により受信モードが設定
された時に、リセット回路６によって記憶回路７がリセ

された後、Ａ／Ｄ変換器５によシ、受信信号の強度を表
わす受信強度データに変換され、記憶回路７に記憶され
る。Further, when the reception mode is set by the changeover switch 10, the memory circuit 7 is reset by the reset circuit 6, and the previously stored data is erased. The received signal, which has been subjected to signal regeneration processing in the receiving circuit 2, is also supplied to the automatic gain control circuit 4, and after being amplified to a predetermined amplitude level, the received signal is transferred to the A/D converter 5. The signal is converted into reception strength data representing the strength and stored in the storage circuit 7.
次に、切換スイッチ１０を送信モード側へ切換えると、
アンテナ１の接続端子Ｃが送信回路３の出力端子すに接
続され、送受話器９の接続端子ｆが送信回路３０入力端
子−に接続される。Next, when the changeover switch 10 is switched to the transmission mode side,
A connecting terminal C of the antenna 1 is connected to an output terminal of the transmitting circuit 3, and a connecting terminal f of the handset 9 is connected to an input terminal of the transmitting circuit 30.
したがって、送受話器９からの音声信号は、送信回路３
で所定の信号処理がなされ、アンテナ１を介して送信さ
れる。Therefore, the audio signal from the handset 9 is transmitted to the transmitting circuit 3.
The signal is subjected to predetermined signal processing and transmitted via the antenna 1.
ここで、制御回路８は、受信モードの際に記憶回路７に
記憶された受信強度データに基づいて送信回路３の送信
出力を制御している。Here, the control circuit 8 controls the transmission output of the transmission circuit 3 based on the reception strength data stored in the storage circuit 7 in the reception mode.
すなわち、記憶回路７の受信強度データの示す強度が大
きい場合には、交信相手が近いので、送信回路３の送信
出力は減少され、受信強度データの示す強度が小さい場
合には、交信相手が遠いので、送信回路３の送信出力は
増゛加される。That is, when the strength indicated by the reception strength data in the storage circuit 7 is large, the communication partner is close, so the transmission output of the transmitting circuit 3 is reduced, and when the strength indicated by the reception strength data is small, the communication partner is far away. Therefore, the transmission output of the transmission circuit 3 is increased.
なお、記憶回路７は、前記説明したように、切換スイッ

受信信号の強度が変化するような場合であっても、常に
適切な送信出力が設定される。Note that, as described above, the storage circuit 7 is reset each time the changeover switch 10 is switched from the transmission mode to the reception mode, so that the latest reception strength data is stored. From this, for example, communicating while moving,
Even when the strength of the received signal changes, an appropriate transmission power is always set.
以上説明したように、この実施例によれば、切換スイッ
チ１０による送受信モードの切換えだけで、自動的に、
交信相手との距離に応じた送信出力が設定されるので、
操作性が良く、しかも、トランシーバの消費電力が低減
される。As explained above, according to this embodiment, simply by switching the transmission/reception mode using the changeover switch 10, the
The transmission power is set according to the distance to the communication partner, so
The operability is good, and the power consumption of the transceiver is reduced.
