Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a high-frequency switch and a mobile communication device using the same, and more particularly, to a high-frequency switch having a filter between a transmission terminal and an antenna terminal and a mobile communication device using the same. .

[0002]

2. Description of the Related Art Conventionally, a method of sharing an antenna for transmission and reception in a mobile communication device has been to use a duplexer constituted by a filter or a high-frequency switch constituted by a semiconductor switch element. However, in order to improve the performance of the mobile communication device, there is a demand for a duplexer or a high-frequency switch that can be easily reduced in size, performs transmission and reception with lower loss, and improves reception quality.

FIG. 10 shows a configuration of a conventional duplexer. The duplexer 50 includes a transmitting terminal 51 and a receiving terminal 5.
2, the antenna terminal 53, the tip short-circuited dielectric coaxial resonators 54a to 54f, and the capacitors 55a to 55h. Then, the tip short-circuited dielectric coaxial resonators 54a to 54c
And the capacitors 55a to 55d form a transmission filter 56 having a pass band at the transmission frequency and a stop band at the reception frequency. The short-circuited dielectric coaxial resonators 54d to 54f and the capacitors 55e to 55h The reception filter 57 has a pass band in frequency and a stop band in transmission frequency.

The operation of the conventional duplexer 50 configured as described above will be described. At the transmission frequency,
Since the impedance when the transmission filter 56 is viewed from the transmission terminal 51 side is low impedance, and when the reception filter 57 is viewed from the antenna terminal 53 side is high impedance, the transmission signal input from the transmission terminal 51 is And is not output to the receiving terminal 52. At the reception frequency, the impedance when the transmission filter 56 was viewed from the antenna terminal 53 side was high impedance, and the impedance when the reception filter 57 was viewed from the antenna terminal 53 side was low impedance. The reception signal is output from the reception terminal 52 and not output to the transmission terminal 51.

FIG. 11 shows a configuration of a conventional high-frequency switch. The high-frequency switch 60 includes a transmission terminal 61, a reception terminal 62, an antenna terminal 63, a control terminal 64, a PI
N diodes 65a and 65b, a transmission line 66 that becomes a quarter of the wavelength at the signal frequency, and an inductor 67
And capacitors 68a to 68d. The inductor 67 and the capacitor 68b form a control circuit, and the capacitor 68b grounds one end of the inductor 67 at high frequency. Also, the capacitors 68a, 68c,
68d functions as a DC block.

The operation when the conventional high frequency switch 60 configured as described above is used as a transmission / reception switch will be described. At the time of transmission, a positive voltage is applied to the control terminal 64. The control current includes a control terminal 64, an inductor 67, a PIN diode 65a, a transmission line 66,
It flows in the order of the IN diode 65b. Along with that, P
The impedance between the anode and cathode of the IN diodes 65a and 65b is low. Since the impedance between the anode and the cathode of the PIN diode 65b is in a low impedance state, one end of the transmission line 66 connected to the anode of the PIN diode 65b is almost connected to the ground potential. The impedance at the other end of the transmission line 66 becomes extremely high.
As a result, the transmission signal input from the transmission terminal 61 is output from the antenna terminal 63 and is not output to the reception terminal 62. On the other hand, during reception, no voltage is applied to the control terminal 64. Therefore, no control current flows, and a high impedance state is established between the anodes and cathodes of the PIN diodes 65a and 65b. As a result, the reception signal input from the antenna terminal 63 is output from the reception terminal 62 and is not output to the transmission terminal 61.

As described above, the antenna can be shared between transmission and reception by the conventional duplexer or high-frequency switch.

[0008]

However, in a conventional duplexer, when transmission and reception frequencies are allocated at narrow intervals, the transmission filter and the reception filter need to have steep attenuation characteristics. Since the number of filter stages is increased, there is a problem that signal loss increases and it is difficult to reduce the shape.

In a conventional high-frequency switch,
The PIN diode to be used must be selected according to the output voltage of the application to be used.
When the harmonic distortion characteristic of the N diode is prioritized, the insertion loss and the switching time are sacrificed, and the PIN diode having the good harmonic distortion characteristic has a problem that the cost is high because the price is high.

, A terminal F1b, an inductor L1 and a capacitor C3. Then, the inductor L1 is connected between the first terminal F1a and the second terminal F1b.

Further, one end of the inductor L1 is connected to the first terminal F1a and to the ground via the capacitor C3. The other end of the inductor L1 is connected to the second terminal F1b.

As shown in FIG. 4, the second switch SW2

Is applied as a forward bias voltage to the diode D2 of the switch SW2, and the diodes D1 and D2 are turned on. Therefore, the transmission signal from the transmission terminal Ttx is transmitted from the antenna terminal Tant, and the transmission line SL3 of the second switch SW2 is connected to the diode D2.
