可变电容元件、高频设备以及通信装置
Abstract:
本实用新型涉及可变电容元件、高频设备以及通信装置。铁电体电容器(C1～C6)构成一个串联电路，该串联电路的第一端与端口(P11)连接，第二端与端口(P12)连接。电阻(R31、R32、R33)构成第一电阻分压电路(RDV1)，电阻(R34、R35)构成第二电阻分压电路(RDV2)。电阻(R31、R32、R33)的共用连接点(CC1)与接地端子(GND)之间的电压作为针对铁电体电容器(C1～C4)的控制电压而被施加。另外，电阻(R34、R35)的共用连接点(CC2)与接地端子(GND)之间的电压作为针对铁电体电容器(C5、C6)的控制电压而被施加。
Abstract(English):

The utility model relates to a variable capacitance element, a high-frequency device and a communication device. Ferroelectric capacitors (C1-C6) form a series circuit. The first end of the series circuit is connected with a port (P11). The second end of the series circuit is connected with a port (P12). Resistors (R31, R32 and R33) form a first resistance voltage division circuit (RDV1). Resistors (R34 and R35) form a second resistance voltage division circuit (RDV2). A voltage between the common connection point (CC1) of the resistors (R31, R32 and R33) and a grounding terminal (GND) is applied as a control voltage aimed to the ferroelectric capacitors (C1-C4). In addition, a voltage between the common connection point (CC2) of the resistors (R34 and R35) and the grounding terminal (GND) is applied as a control voltage aimed to the ferroelectric capacitors (C5, C6).
