Introduction The Taoglas HC125A is a low profile, high performance, 3dB hybrid coupler in an easy to integrate surface mount package. It is designed for multi feed GNSS applications. The HC125A is particularly used for applications where balanced power and low noise amplifiers are required. It has low insertion loss and tight amplitude and can be used in power applications up to 30 Watts. It has been engineered to cover the full GNSS bandwidth of 1150 – 1630MHz. Introduction The HC125A has been subjected to rigorous qualification testing and it is manufactured using materials with coefficients of thermal expansion (CTE) compatible with common substrates such as FR4, G-10, RF-35, RO4350 and polyimide. Introduction The HC125A is the perfect companion to ensure successful integration of multi feed high performance, high precision GNSS patches from Taoglas such as the full band GPDF5012.A or the dual L1 feed GPDF254.A. Integration details are included in specific product datasheets but for further information regarding the HC125A or it’s integration with any of our antennas, please contact your regional Taoglas customer support team.

Once port one has been identified the other ports are known automatically. Please see the chart below for clarification: 4. Antenna Radiation Patterns 4. Antenna Radiation Patterns 4. Antenna Radiation Patterns 4. Antenna Radiation Patterns 4. Antenna Radiation Patterns 4. Antenna Radiation Patterns 4. Antenna Radiation Patterns Note: The “A” is the amplitude of the applied signals. When two quadrature signals with equal amplitudes are applied to the coupler as described in the table, they will combine at the output port. If the amplitudes are not equal, some of the applied energy will be directed to the isolated port. SPE-20-8-104-C www.taoglas.com 7 5. Typical Performance (-55°C, 25°C, 95°C, 125°C: 1150-1630 MHz) .
