Waveguide Combiners & Dividers		See Also: W/G Couplers, Broadwall Directional Coax Power Dividers & Combiners
ATM manufactures Waveguide Short Slot Hybrid Combiners/Dividers in a choice of configurations. These units are useful in applications where smaller sizes are required. For applications where full band width is needed or for uneven power distribution of values other than 3dB, ATM manufactures Broadwall Coupler Combiners/Dividers which utilize a multi-hole coupler design resulting in full band width. Feel free to call us and discuss your needs with one of our design engineers.
