RF Directional Couplers are devices used to measure the amplitude and phase of a signal in a transmission line or other waveguide. They can also be used to separate a signal line from a power line, or even two power lines. The 10930-10 is a unique type of directional coupler, designed to measure the low level signal (<5W) of a VHF base station in a frequency range from 30 to 400 MHz. It utilizes an advanced silicon MMIC (Monolithic Microwave Integrated Circuit) technology coupled with an innovative mechanical design to enhance performance while keeping cost to a minimum. This article explores the application field and working principle of the 10930-10 RF Directional Coupler.
Application Fields for the 10930-10 RF Directional Coupler
The 10930-10 RF Directional Coupler is an invaluable tool in the field of VHF base station testing. It has two primary uses for VHF base stations: isolating the antenna from the transmitter, and measuring the RF signal power in an antenna line.
The isolator mode of the 10930-10 is especially useful when there is a problem with an antenna, transmitter, or power line. It allows technicians to separate the antenna line from the transmitter line, then measure the signals in the antenna line. This data can then be used to diagnose the cause of the problem.
The power measurement mode is used to measure the power level of an RF signal in an antenna line. This information can be used to confirm that a base station is operating within the legal power limits, or to diagnose a decrease in signal quality. The 10930-10 is especially useful in this mode because it is designed to measure lower level signals, of up to 5W.
Working Principle of the 10930-10 RF Directional Coupler
The 10930-10 RF Directional Coupler utilizes an advanced silicon MMIC (Monolithic Microwave Integrated Circuit). The MMIC consists of a number of very small circuits combining to form a single device, which can be used for any number of purposes. In the case of the 10930-10, the MMIC is specifically designed to measure low level RF signals.
The 10930-10 also utilizes a unique mechanical design. This design consists of a ‘bridge’ which consists of two arms, each of which contains a section of cable or inductor. One arm is connected to the common terminal of the coupler, and the other arm is connected to the the input terminal. When a signal passes through the bridge, it produces a voltage drop across the arm connected to the common terminal. This voltage drop is then used to measure the power of the signal.
The 10930-10 also utilizes a pair of baluns (balancing transformers) to ensure that the isolation mode is maintained between the input and output ports. This maintains the integrity of the signal measurement and eliminates the possibility of signal leakage in the transmission line.
Conclusion
The 10930-10 RF Directional Coupler is a versatile and useful tool for testing VHF base stations. It utilizes an advanced MMIC technology coupled with an innovative mechanical design to measure low level signals in the range of 30 to 400 MHz. Its two primary uses are isolating the antenna from the transmitter and measuring the RF signal power in a transmission line. This article has given an overview of the application field and working principle of the 10930-10 RF Directional Coupler.
