Millitech series MUT frequency triplers are balanced resistive - mode multipliers covering full waveguide bands. Power flatness over the full waveguide band for a given input power level is typically ±2.0 dB.

These triplers are offered in both a standard low power and a high power version. The standard version operates with 16 dBm input power and typically provides -2 to +2 dBm of output power depending on frequency. The high power version operates with +20 dBm of input power (+17 dBm for higher frequency bands) and provides -3 to +5 dBm output power depending on frequency and input power. (see performance tables on the following page). Input VSWR is 2.5:1, second harmonic content is less than -30 dBc, and fourth harmonic content is less than -20 dBc typically.

Both versions operate over a wide range of input power levels, and can be tested at customer-specified power levels. These frequency triplers can be optimized to produce higher output power over narrower-than-full waveguide bandwidth. They are compact in size, typically less than a cubic inch, and require no external DC bias.

Series MUT triplers are particularly useful for extending the use of test equipment into millimeter-wave bands. They are capable of generating enough power to pump biased mixers or detectors, or to lock injection-lockable oscillators and amplifiers.
