LDC-4/40-90S 4-40Ghz 90 Degree hybrid coupler combiner

Ldc-4/40-90s 90 Degree Hybrid Coupler with 2.92mm connectors**, based on standard industry nomenclature and the information provided in the model number:Core Function: 90-Degree Hybrid Coupler (Quadrature Hybrid)
What it does: This is a passive RF/microwave component with four ports. Its primary functions are:
Splitting: Divides an input signal (applied to one port) into two output signals of equal magnitude but with a 90-degree phase difference** between them.
Combining:Combines two input signals (with a 90-degree phase difference) into a single output signal at the isolated port.
Key Characteristic: The consistent 90-degree phase shift between its outputs is crucial for applications like image-reject mixers, phase shifters, balanced amplifiers, and signal generation/processing circuits.
