The QK- 661 is the first tube of its kind to cover the entire government band. The QK-754 is the first of a planned series of tubes to cover the entire communications band. Both are mechanically tuned, integral- cavity, long-life, reflex-type tubes. The QK-754 uses a coaxial output; the QK-661, Typical operating characteristics a waveguide output.

Men, machines, and manufacturing know-how from other TRW divisions will be added as needed to build up the growing production strength of the Ramo- Wooldridge division. In other ways, too, the availabil- ity of the special skills and facilities of the rest of the corporate family will broaden the services R-W can offer to its customers.
