1. Simple, Efficient Microwave Hybrid Power Dividers By Robert J. Templin W5OE Roadrunners Microwave Group

2. Reasons for Hybrids EME and other applications require higher microwave power High power MW amps are TWTs or other high voltage devices not happy to sit out at the antenna feed point

3. Reasons for Hybrids With high-power MW amps in the shack, line losses are significant A 200 W amp in the shack with a 3 db line loss is only 100 W at the feed

4. Reasons for Hybrids High power MW solid state amps operate at 28 volts and can be placed at the feed point Line losses are eliminated High power MW amps can be combined with hybrids to outpower TWT’s

5. Eu design Hybrid Combiner

6. N6CA 23cm ring-hybrid using tubing for the ring - Tubular ring element is a problem for other bands

7. N6CA design ring-hybrid using flat stock for ring - Easy to adapt to any band

8. Critical Dimensions Radius A Radius B Radius C Spacing 1.5 Divided by 2  (0.2387 free space ) Radius A minus.125” Radius A plus.125” 0.100” for all bands

9. Critical Dimensions Connector electrical spacing 90, 90, 90, 270 degrees Linear Spacing A, A, A,2A

11. Precautions Microwaves at high power levels deserve biological care! You wouldn’t stick your head in a microwave oven, don’t get near high power feeds!
