MUD frequency doublers featuring Millitech technology are balanced resistive-mode multipliers covering full waveguide bands. Power flatness for a given input power level for these units is typically ± 2.0 dB across the band.
These doublers are offered in both a standard and a high power version. The standard version operates with 16 dBm input power and typically provides 0 to +3 dBm of output power depending on frequency. The high power version operates with +20 dBm of input power and provides +2 to +5 dBm output power depending on frequency (see performance tables on the following page). Input VSWR is 2.5:1 and third harmonic content is -25 dBc typically.
Both versions operate over a wide range of input power levels, and can be tested at customer-specified power levels. These frequency doublers 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.
