4243-20

The 4243-20 Frequency working RF Directional Coupler is a compact, reliable, dependable, and durable solution available to perform measurement and analysis of an RF signal path. This device is effective in measuring forward, reverse, and cross-directional components in the RF signal path. This RF directional coupler offers great power measurement accuracy when measuring the various parts of an RF signal path, and is especially useful in maintaining a stable signal path between sources and receivers.

The 4243-20 RF Directional Coupler utilizes the proven technology of a matched transmission line inserted between two terminals to measure forward, reverse, and cross-directional power in an RF signal path. This type of device reflects the perfectly matched transmission line\'s characteristic impedance to the incoming signal at port A. The energy at port C is reflected back as a signal with the same magnitude, causing the forward and reverse power components to be equal. The reflected power is then measured at port B.

The 4243-20 RF Directional Coupler has been designed to have a wide dynamic range to cover a range of RF signals from 30 MHz to 3 GHz and a nominal power rating of 40 dB. The device covers a broad frequency range from 30 MHz to 3 GHz with a loss of only 0.15 dB, consequently, it is suitable for many applications. The coupler has a nominal insertion loss of 0.2 dB from the input to the output, ensuring that minimal power loss occurs in the signal path. The insertion loss also provides power matching from the input to output and provides very good power reflection performance.

The 4243-20 RF Directional Coupler is designed to measure the amplitude and phase of RF signals in both forward and reverse directions. The main advantage of this type of coupler is that it operates without disturbing the power and phase characteristics of the RF signal. The overall design results in a very accurate powerdB and phase measurement which can be easily compared to any reference standard. The device also maintains a very low amplitude error over a wide frequency range of 200 kHz to 3GHz.

The 4243-20 RF Directional Coupler has many advantages over other coupler designs. First, the design maintains a lower insertion loss than conventional couplers. Secondly, it offers excellent power returning performance, minimizing signal loss from forward, reverse, and cross-directional components. Thirdly, it can provide high-resolution power and phase data measurement, enabling precise characterization of the RF signal path. Finally, its design allows for effective isolation between the output and port A, minimizes signal leakage, and ensures consistent signal paths.

The 4243-20 RF Directional Coupler is an essential component in test and measurement equipment. Its design enables accurate and reliable power measurement in various applications. It is very useful for providing stability and protection against signal distortion and interference of RF signals. The 4243-20 RF Directional Coupler is an ideal device for engineers that require a reliable and cost-effective solution for their measurement challenges.
