望まれていた。This kind of power booster is inserted between a transmitter or a transmitter and a receiver and an antenna to increase transmission power. Normally, however, an input part and an output part are directly connected to the inside of the power booster as shown in FIG. It is equipped with a through circuit that automatically connects the antenna directly to the main unit when the booster power is turned off. In the transceiver, even when the booster power is on,
A command control voltage is applied from the transmitter side, the booster operation is stopped at the time of reception, the booster is switched to a through circuit, and the same antenna is used for both transmission and reception so that the operation is performed without trouble. Furthermore, for multiple bands, it is necessary to select a booster in the same band as the main band used. For this reason, a command control line is provided between the transmitter body and booster, and in the case of stationary equipment there is no problem because it only needs to be connected once, but in the case of vehicles it is often removed to prevent theft. However, there is a problem that an extra connection is required each time, which easily causes an accident, and when a booster is installed in a trunk, a long control line is required. Was wanted.

In the figure, in the power booster 3 inserted between the transmitter or the transmitter / receiver main body 1 and the antenna 2, when the main body 1 operates in the frequency A band and the frequency B band, the booster 3 also has an A band amplifier. The first relay 33 , which includes 31 and B-band amplifiers and is provided at the input part and the output part of the booster 3 , has both the input side 33A and the output side 33B normally turned on a side and normally turned off b side. When the power of the power booster 3 is cut off, the input circuit 331 is directly connected to the output circuit 333 through the through circuit 332. Next, even if the power of the power booster 3 is turned on, if the main body 1 is not in the transmitting state, the relay 33 holds this state, and reception can be performed through the through circuit 332.

幅器３８を導通してリレー３３をｂ側に切り替える。When the A-band radio wave is output from the main unit 1 during transmission,
Since a rectified power voltage is generated in the rectifier 36A that is subordinate to the bandpass filter (hereinafter referred to as BPF) 35A that passes through the A band that is in contact with the power booster 3 input circuit 331, this is added to the control amplifier 38 that is normally OFF. To conduct. Since the conduction current is supplied from the power supply V CC through the relay coil 33C, the relay 33 is switched to the b side. When the B band is used, the BPF 35B and the rectifier 36B operate, and the rectified output conducts the control amplifier 38 through the backflow prevention diode 37 to switch the relay 33 to the b side.

If 34 is normally turned on to the 31st side of the A band, it can be left as it is when the A band is used. Only when the B band is used, the control amplifier 39 is conducted by the output of the rectifier 36B and the relay coil 34C is energized, and the relay 34 is turned to the b side. Switch. Contact 34D at the same time
Also switches the power supply of the amplifier. However, if the band relay operation is simply controlled by the electric wave, the relay operates when the electric wave is momentarily interrupted, so that the relay 34 will be described as a self-holding circuit with reference to FIG. In FIG. 2, the same parts as those in FIG. 1 are indicated by the same symbols, and the description of the points described in FIG. 1 will be omitted.

衰させる効果もある。The transmitter or transceiver main unit 1 has a 144MHz band and 43
It is a dual band amateur radio for the 0MHz band and antenna 2 is a dual band antenna for the 144MHz and 430MHz bands. In the power booster 3 ,
BPF 35A passes between 144MHz and 146MHz, and BPF 3A
5B passes between 430 and 440 MHz. The purpose is to detect the presence or absence of the radio wave input of the corresponding band in the subsequent rectifiers 36A and 36B, so that the out-of-band attenuation of 20 dB is sufficient, and both bands are sufficiently separated. There is no problem in separation detection.
Therefore, the BPF may be a ladder type, but in this example, the two tuning circuits T 1 and T 2 are connected to the capacitor C 0 as the simplest configuration example.
In the bound double-tuned circuit, the capacitance C 1 and C 2 and the external circuit
Are joined by. It is desirable that the capacitances C 1 and C 2 be as small as possible in order to avoid the influence of external circuits, but since the input wave level is high, it also has the effect of attenuating to the operating level of the rectifier diode.
整流器３６Ａ・３６Ｂは倍電圧整流形であるが、これは
出力電圧を倍増するためではなく、外部回路を簡単に
し、アタック時定数を小さくできる効果がある。The rectifiers 36A and 36B are voltage doubler rectifiers, but this is not for doubling the output voltage, but has the effect of simplifying the external circuit and reducing the attack time constant.

２の電源もOFFとなる。The control amplifiers 38A and 38B have collector current cut-off in the non-input state, and since they use NPN type transistors in the illustrated example, they conduct with positive rectified output. When 38A is conducted, the collector current is diode 41A and relay coil 3
Since it flows through 3C, the contacts 33A and 33B of the relay 33C are inverted and the antenna circuit is switched from contact a (through) to contact b.
(Booster) is switched to, and at the same time, the power of the booster amplifiers 31 and 32 is turned on at the contact 33D. When the transmission radio wave of the main body 1 is stopped, the contact 33A of the relay 33 is immediately
33B returns in the order of contact a (through), and the amplifier 31.3
The power of 2 is also turned off.

が確実・安定である長所がある。Relay 42 is 144MHz band amplifier 31 and 430MHz
A self-holding (latch) type relay that selects the band amplifier 32. The contact 42A switches the input section, the contact 42B switches the output section, and the contact 42D switches the power supply. Since this type of relay is bistable, the contact should be turned on to the c side or d
A setting circuit for turning on the side is required. Since the switching control signal is output by the transistors 38A and 38B of the control amplifier, the transistor 40A of the electronic switch circuit is used.
-By forming a bridge circuit with 40B and connecting a relay coil 42C between its equilibrium points, the transistor 38A becomes conductive and the collector potential drops when operating at 144MHz, bringing the base potential of the transistor 40 close to the collector potential. Transistor 40B becomes conductive, the current is 40
It flows in the direction of B → 42C → 38A. At this time, the contact of the relay 42 selects the c-side 144 MHz band, and the contact is kept as it is even if the radio wave stops. Next, when the 430 MHz band is input, the transistor 38B becomes conductive, the base potential of the transistor 40A approaches the collector potential and the transistor 40A becomes conductive, and the current flows in the direction of 40A → 42C → 38B, and the current passing direction of the relay coil 42C becomes Since it will be the opposite, it is reversed to the contact d side of the relay 42 and 430 MH
It becomes the z band, and is held as it is until the next 144 MHz band is input. The self-holding of the relay can be configured by an electronic circuit, but the self-holding type relay has an advantage that the operation is reliable and stable.
