Product Description

KRYTAR specializes in the design and manufacturing of ultra-broadband, high performance microwave components and test equipment for both commercial and military space applications. Products manufactured for Space Applications undergo additional reliability and quality assurance inspections during all phases of assembly, electrical evaluation, and shock/vibration testing. Parts, materials and processes are fully traceable from subordinate to top-level assemblies. KRYTAR can also provide customized solutions to meet your application-specific requirements. Our successful space heritage offers qualities you can depend on including: offering innovative products, quick-reaction capability, design responsiveness, flexibility, fast production turn-around, and partnerships with our customers.

KRYTAR 180 Degree Hybrid Couplers are four-port components with dual input and output ports.

KRYTAR’s hybrid couplers offer wide frequency coverage in single, compact packages, which provide low insertion loss, high directivity and tight coupling. These hybrid couplers offer simple solutions in many applications within those frequency bands including Space, electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments. For many space-restricted situations the compact size of these KRYTAR couplers are ideal.

These couplers can also be manufactured to meet military specifications.

KRYTAR’s new hybrid coupler, Model 4010265-SQ, delivers exceptional versatility from 1.0 to 26.5 GHz with excellent phase and amplitude matching. Typical specifications include 3 dB Coupling; Amplitude Imbalance: ±1.0 dB (1-20 GHz) and ±1.5 dB (20-26.5 GHz); Phase Imbalance is ±16-degrees; Isolation is >15 dB; Maximum VSWR: 1.80 (1-20 GHz) and 1.95 (20-26.5 GHz); and Insertion Loss of ±3.0 dB (1-20 GHz) and ±3.6 dB (20-26.5 GHz).

In addition, Model 4010265-SQ offers Input Power Rating of 20 W average and 3 kW peak. The hybrid coupler comes with industry-standard SMA Female Connectors. The compact package measures just 4.04 inches (L) x 1.35 inches (W) x 0.52 inches (H), and weighs only 4.6 ounces. Operating temperature is -54° to 85° C.

KRYTAR also offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications.

Power Dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit.

MLDD signifies Matched-line Directional Divider, a new class of microwave directional devices invented and patented by Thomas J. Russell, the founder of KRYTAR.

Directional Couplers: Components that allow two microwave circuits to be combined into one integrated system in one direction with the two completely isolated from each other in the opposite direction.

Couplers are passive microwave components used for distributing or combining microwave signals. Directional couplers are four-port circuits where one port is isolated from the input port.

The coupled port on a microstrip, or stripline directional coupler, is closest to the input port because it is a backward wave coupler. On a waveguide broadwall directional coupler, the coupled port is closest to the output port because it is a forward wave coupler.

VSWR (Voltage Standing Wave Ratio) is is defined as the ratio of the maximum voltage to the minimum voltage in standing wave pattern along the length of a transmission line structure. It varies from 1 to (plus) infinity and is always positive.

Insertion Loss is the net unrecoverable power in dB dissipated within the circuit at any frequency within the specified range.

Frequency Sensitivity is the amount of frequency change in the carrier frequency per unit amplitude change in the message signal.
