Active Components

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.

Single-Pole Double-Throw PIN Switch (PDT)

PDT PIN diode switches featuring Millitech technology is available in seven waveguide bands from 18 to 100 GHz and in either Y or I configurations. All switches are offered with integrated drivers, and can be operated with a standard TTL input. Series Switches are also offered in PSP single-pole, single-throw (SPST) switches and series PSH high speed switches series PS3 (SP3T) and PS4 (SP4T) models.

Active Multiplier Chain (AMC)

The series AMC line of active multipliers featuring Millitech technology extends the range of sources from 7.5 to 20 GHz coaxial to the complete millimeter-wave spectrum from 26 to 140 GHz.

Switched Filter Banks

Switched Filter Banks typically include multiple filter topologies, including PIN diode and MMIC switch sub-circuits to achieve operational bandwidths of greater than 3 octaves. Pin Diode Based Switched Filter Banks provide the highest level of signal isolation, higher operating power levels, and lower insertion loss and achieve switching speeds of < 40 nanoseconds. GaAs MMIC Based Switched Filter Banks provide switching times as low as 10 nanoseconds with very low power consumption and have the inherent advantage of supporting multi-octave frequency bands with extremely low power consumption.  


Offering synthesizer architectures supporting operating frequencies from 0.1 to 40 GHz. Our direct analog and digital designs feature fast switching speed of less than 100 nanoseconds and ultra-low phase noise. Our wideband indirect synthesizer designs support your requirements for smaller size and lower power consumption and offer typical switching speed of less than 500 microseconds. Composite architecture designs (Direct and Indirect Synthesis) are also available to optimize phase noise, switching speed, size and power consumption. 

Up/Down Frequency Converters

Smith Interconnect's frequency converters provide frequency translation of the input signal to a desired output frequency. They support up and down frequency translations with either fixed local oscillators (block converters), or tunable local oscillators (agile converters). Its design supports frequency bands from 0.1 to 40 GHz. Contact our product experts to discuss your specific system requirements and custom configurations to meet your needs.
