Product Description

KRYTAR coaxial Dual-Directional Couplers are 4-port couplers that are the combination of two 3-port couplers having their main lines cascaded. This dual-directional design, two back-to-back couplers in the same package, lets you monitor forward and reflected power. It also assures good directivity, flatness, and coupling accuracy. Typical applications include power sampling and measurement, amplifier leveling, VSWR monitoring, field control, and amplifier and load protection.

KRYTAR’s latest addition, Model 501065013, enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling within a ultra-broadband frequency range of 1.0 to 65.0 GHz in a single, compact and lightweight package.

In addition, Model 501065013 offers superior performance ratings including Nominal Coupling (with respect to output) of 13 dB, ±2.0 dB, and Frequency Sensitivity of ±1.5 dB (from 1 to 50 GHz) and ±2.5 dB (from 1 to 65 GHz). The dual-directional coupler exhibits Insertion Loss (including coupled power) of less than 6.5 dB, Directivity of greater than 10 dB (from 1 to 50 GHz) and 7 dB (from 50 to 65 GHz), Maximum VSWR (any port) is 1.8 dB, Input Power Rating is 20 W average and 3 kW peak. The directional coupler comes with industry-standard 1.85-mm Female Connectors. The compact package measures just 5.0 inches (L) x 0.50 inches (W) x 0.65 inches (H), and weighs just 3.9 ounces. Operating temperature is -54° to 85° C.

KRYTAR’s dual-directional coupler is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. KRYTAR couplers offer solutions for many ultra-broadband applications including electronic warfare (EW), commercial wireless including mmWave, 5G, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC (electromagnetic compatibility) testing environments. For many space-restricted applications the compact size makes KRYTAR directional couplers ideal solutions. The directional coupler can also be manufactured to meet ridged military specifications.

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

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.
Dual-Directional Couplers are 4-port couplers that are the combination of two 3-port couplers having their main lines cascaded.

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 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.

mmWave (mm-Wave)
Millimeter wave is the band of spectrum between 30 GHz and 300 GHz. Wedged between microwave and infrared waves, this spectrum can be used for high-speed wireless communications as seen with the latest 802.11ad Wi-Fi standard (operating at 60 GHz). It is being considered by standards organizations, the Federal Communications Commission and researchers as the way to bring “5G” into the future by allocating more bandwidth to deliver faster, higher-quality video, and multimedia content and services.

5G
The fifth generation (5G) of cellular service, superseding 4G LTE. Governed by the 3GPP, 5G will increase transmission speed dramatically and embrace prioritization. As wireless data increases exponentially, real-time content such as video calling and video streaming must be given a higher priority than data on Web pages.

5G NR (5G New Radio)
The 5G air interface, which like 4G also uses OFDM modulation, was designed to deliver data rates up to 20 Gbps, enabling individual users to get gigabit-per-second downloads over the air. Wireless virtual reality (VR) and augmented reality (AR) can become commonplace, and 5G is expected to provide a huge boost for connecting billions of Internet of Things (IoT) devices.
