RF Combiner KINIQ XQY-PS4-2/8-SS

Buy XINQY XQY-PS4-2/8-SS 4-Channel Power Divider/Adder for High Precision RF Systems

XINQY XQY-PS4-2/8-SS is a professional 4-channel power divider/combiner operating in the 2-8 GHz band. The device is made using Microstrip technology at 50 Ohms with SMA-Female connectors. It allows you to split one input signal into four identical outputs or combine four signals into one. This is a reliable solution for telecommunications, radar systems, satellite communications and measurement systems.

• Frequency range 2000–8000 MHz for operation in modern wireless systems.
• Low insertion loss ≤1.0 dB for maximum signal transmission efficiency.
• High isolation up to 25 dB to prevent crosstalk between channels.
• Amplitude imbalance ≤0.3 dB and phase imbalance ±4° for high accuracy.
• Wide temperature range from -45 to +85°C and power up to 30 W in divider mode.

How does a power divider/combiner work?

The device receives the RF signal at the sum port and splits it into four outputs with equal amplitude and phase. In adder mode, it combines signals from four ports into one output. Low VSWR (1.16 on the sum port, 1.14 on the distribution ports) minimizes reflections, and high isolation prevents mutual interference. Microstrip design ensures compactness and stable performance. You get clean and balanced signal distribution for your RF circuits.
