Abstract

The invention discloses a 10MHz-8GHz miniaturization bridge unit characterized by comprising an excitation signal input port P1; the excitation signal input port P1 is connected with one end of a winding b; the winding b and a winding a form a twisted pair winding on a magnet ring, and the magnet ring is also winded by a winding c; one ends, close to the excitation signal input port P1, of the windings a and c are connected and grounded; the other ends of the windings b and c are respectively connected between a resistor R2 and a resistor R3; the other end of the resistor R2 is connected with a resistor R1; an isolation port P2 is arranged between the resistors R1 and R2; the other end of the resistor R1 is connected with a test port P3; the other end of the winding a is connected between the resistor R1 and the test port P3. The 10MHz-8GHz miniaturization bridge unit can solve the problems that the application frequency of an existing twisted pair transmission line magnet ring orientation bridge is hard to raise.

Description

[0001] 【Technical field】

[0002] The invention belongs to the field of test instruments, in particular to a miniaturized electric bridge device suitable for 10MHz-8GHz.

[0003] 【Background technique】

[0004] The vector network analyzer is an important microwave measurement tool, which is widely used in the characteristic measurement of radio frequency microwave devices. Such as: testing of passive components such as attenuators, filters, power splitters and active components such as amplifiers. By transmitting an excitation signal to the device under test, the receiver receives the transmitted signal and the reflected signal to complete the measurement of the device characteristics. These measurement information includes amplitude and phase information, which can be further converted into return loss, transmission gain and insertion loss. In recent years, miniaturized and portable vector network analyzers have been widely used. On the one hand, it is due to the needs of f...
