UHF Gysel Power Combiners

ERI offers in-phase Gysel UHF power combiner in 3-way and 4-way configurations. These combiner systems combine 3 or 4 four cabinet with very low insertion loss while providing high isolation. Gysel combiner require one reject load per input but no power is present at the load unless the system has an amplitude imbalance.

CY316 1x3 Gysel Combiner

Any specified UHF RF Channel (470 to 700 MHz)
3 x 8 kW average power ATSC

The Model CY316 In-Phase Power Combiner consists of a coaxial 3-way Gysel assembly and three, 50-ohm, forced air-cooled oil filled reject loads. A non-directional voltage probe is included at each of the load ports; each is labeled with the measured coupling value at the specified RF Channel. The Power Combiner assembly resides an aluminum base frame, suitable for floor-mounting. The input and output connections are vertical. The three input connections are 3-1/8-inch, 50-ohm EIA flanged. The combined output is a 4-1/16-inch, 50-ohm flanged, male, connection.

In-Phase Gysel Combiner, includes:
(1) 3-way Coaxial Gysel
(3) 5 kW, Forced Air-Cooled Reject Loads
(3) Non-Directional Voltage Probe, 1-5/8-inch
(1) Interconnect components between above items
(1) Aluminum Floor-mount base frame
Inputs: 3-1/8-inch, 50-ohm EIA flange, male, vertical
Output: 4-1/16-inch, 50-ohm flange, male, vertical
Voltage Probe: Type ā€œNā€ female

CY317 1x4 Gysel Combiner

Any specified UHF RF Channel (470 to 700 MHz)
4 x 8 kW average power ATSC

The Model CY317 In-Phase Power Combiner consists of a coaxial 4-way Gysel assembly and four, 50-ohm, forced air-cooled oil filled reject loads. A non-directional voltage probe is included at each of the load ports; each is labeled with the measured coupling value at the specified RF Channel. The Power Combiner assembly resides an aluminum base frame, suitable for floor-mounting. The input and output connections are vertical. The four input connections are 3-1/8-inch, 50-ohm EIA flanged. The combined output is a 6-1/8-inch, 50-ohm EIA flanged, male, connection.
