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. 


Tactical Datalink Communications for Fixed Ground and On-the-Move Applications. The GDT antenna assembly consists of a positioner, controller, and parabolic feed assemblies that provide the critical command, control, and sensor connectivity of the TUAV to the ground control station.


Ground Data Terminal, TCDL antenna system operates from 14.4 – 15.35 GHz in Ku-Band. The antenna system is currently fielded, operationally proven and qualified for TUAV’s. The antenna system includes a 4-foot reflector, Ku-Band feed, antenna positioner with integrated servo and control systems electronics, and tripod assembly. Transit cases can also be supplied to protect these assemblies while in transit to the operations site Smith Interconnect’s microprocessor-based Antenna Control Unit (ACU) is designed to provide cost-effective control of the antenna positioner assembly. The integrated controller can operate over an RS-232, RS-485, Ethernet or Fiber Optic interface.

Isolators and Circulators

High power devices feature composite adiabatic technology designed for optimum thermal handling without compromising the careful electro/magnetic balance required to achieve leading performance while optimum isolation performance and reverse power handling is achieved by using a suite of high power resistive elements which utilize film technologies. All designs are vented with the position of the vents optimized as a result of careful analysis and design proving tests.

ITAR Isolators and Circulators in L, S and X-Bands

L, S & X-Band high power Circulators and Isolators are specifically designed for solid state power amplifiers (SSPA) used across various Military Communication and Radar applications.

Loads, Terminations and Attenuators

Smiths Interconnect produces a wide variety of loads and terminations ranging from those designed to be integrated into isolators to stand alone components. Loads, terminations and attenuators conjure images of assemblies used in applications with impressive levels of RF power. 

Microstrip Isolators and Circulators

Microstrip isolators and circulators are broadband structures that offer low profile wire-bondable interfaces with broad band operation and low mass. Together this makes microstrip devices ideal for use in hybrids for space and terrestrial AESA applications

Mobile Multi-band Antenna

MMA-RX utilizes a three aperture design providing Quad band Data receive bandwidth in a single unit. The system features upgraded high efficiency apertures providing short to medium range link capability. The desired aperture is user selectable On-The-Fly through a flexible software interface, providing L/S, or C, or Ku Band capability within 3 seconds.

MW Waveguide to Coaxial Transitions

Smiths Interconnect offers a wide range of transitions and iso-adapters (a transition integrated with either a coaxial or waveguide isolator. Devices are available from S to E-Band and designed specifically for their intended application power handling and operating environment.
