Best Microstrip Directional Coupler Manufacturers – 100W Cavity Directional Coupler 70-500MHz Ultra-wideband Microuwave Directional Coupler N-Female Directional Coupler – Keenlion Detail:
Product Overview
1. 10dB 50ohm Directional Coupler N-Female connectors full-band 70-500MHz
2. The 10dB Directional Coupler can continuously sample the transmission power along a certain direction of the transmission line, and can divide an input signal into two signals with equal amplitude and 90°phase difference.
3. Port Connectors: N-female connector.
4. The design is simple and compact, easy to carry and easy to install.
5. DC current pass through input to output
6. Applications: lab use, VHF and UHF, Defense
7. Model Number: KDC-70/500-10N
8. 70-500MHz 10dB PIM3 Directional Couplers are passive four port devices which are used to couple part of the signal travelling in one transmission line to another port. They are typically used for sampling signals in a system. Directional couplers can be developed using a number of techniques – striplines, lumped element or discrete elements.A directional coupler has four ports –Port 1 – Input, Port 2 – Output, Port 3 – Coupled Signal Port, Port 4 – Isolated Port.
The power that is passing from the input (port 1) to the output (port 2) is coupled with a coupled line and passes out through the coupled output port (port 3), which is isolated from the main output port (port 4). Any reflected power from the main output is coupled to the port that is terminated, resulting in minimal reflections within the device/system. The power level of the coupled signal is a parameter to be selected based on the requirement.
Key Features
Feature |
Advantages |
Wide bandwidth |
With a bandwidth spanning 70 to 500MHZ, Directional coupler is ideal for most lab testing applications, avoiding the need to switch components for different frequency bands. |
Excellent Directivity • 12 dB typ |
High directivity allows sampling of input powers with minimal detrimental effects due to output mismatches. |
Excellent coupling flatness, 10±1 dB typ | Excellent coupling flatness over the entire frequency range minimizes the need for compensation circuits in most cases. |
VSWR 1.3: 1 typ. |
Good VSWR over 70 to 500MHZ minimizes undesired reflections and resulting amplitude ripple. |
