When using the portable device section A mounted on a car, conventionally, as shown in Fig. 1, the band device section 11a is connected to the in-vehicle adapter section H by a switch (61) to transmit data to the portable device section. Conventional in-vehicle and portable radios, which were used by increasing the output with the in-vehicle adapter B and improving the reception sensitivity, are configured as described above. A transmitting/receiving duplexer (3) is required, and a duplexer T7+, +l is also installed in the vehicle adapter section B.
f1 is required, which has the disadvantage that not only the transmission loss of the high frequency signal system becomes large, but also the volume and weight become large.

In the figure, α go is a portable transmitting antenna, and (13) is a portable receiving antenna, which are attached to the terminals of the transmitter (21) and receiver (4) of the portable unit A, respectively, so that they can be used when carried. Antenna is used. 1lli 2 antenna system is adopted.
), the portable unit A is connected to the in-vehicle adapter part B, and the transmitter (2) and the transmitting amplifier (8) are directly connected for transmission. In addition, in the case of reception, the receiver (
4) and a receiving amplifier (9) are directly connected and used.

機が構成できる。Next, the operation of the apparatus of the present invention will be explained. Portable unit A with a two-antenna system may require a filter to remove unnecessary waves in the high-frequency parts of the transmitter (21) and receiver (4), but it is not possible to use a filter as in the one-antenna system shown in Figure 1. A transmission/reception duplexer (3) is not required.Therefore, when using a two-antenna type portable unit A in a car, the duplexer (7) of the car adapter part B as shown in Fig. 1 is used as a relay. without transmitter (
The output of 21 can be directly connected to the transmitting amplifier +81, and since there is no transmission loss of the duplexer (:3) and (71) shown in Figure 1, it can be easily amplified to the required power. .In addition, the received signal is also passed through a demultiplexer (7) as before.
By transmitting the signal directly from the receiving amplifier (9) to the receiver (4) without going through (3), there is little deterioration in the sensitivity of the receiver (and if the receiving amplifier t9+ is not required due to the circuit design) In this way, by using the two-antenna system for the portable unit A, there is no need for a duplexer in the portable unit A and the vehicle adapter unit B, and a compact, lightweight, and economical radio device can be constructed. .
