New Surface-mount Couplers Designed for Defense Applications
It goes without saying that components and sub-assemblies supporting today’s defense equipment, such as military radio receivers and counter-IED solutions, must be rugged, light and reliable. Increasingly critical, however, are a host of beyond-requisite demands that reflect today’s new military procurement and combat realities. One example is the dictum that communications technologies must operate over wider and more numerous frequency bands in support of the equally wide variety of electronics being deployed at the warfighter level and across all branches of the military. Then there is the intense downward pressure on procurement costs and bills of materials, ironically paired with intense upward pressure to pack ever-more functionality into the ever-smaller gear being deployed to today’s multi-mission armed service members.
Anaren has recently introduced a new family of couplers designed specifically for both these traditional and emerging requirements. Leveraging its original innovation and subsequent track record in multilayer, stripline components in the commercial wireless infrastructure sector, the company has expanded its popular Xinger®-brand packaging approach to the military side with three new couplers specifically designed to cover the wide range of frequencies utilized by military equipment OEMs, while reducing both cost and component footprints.
Pushing the frequency of operation up to 6 GHz, Anaren’s new wideband couplers are available in three formats—the smallest measuring only 0.20 0.56 0.089 inches—and, like their commercial-grade counterparts, are 100 percent RF tested and fully compatible with high-volume, automated pick and place equipment. They are the first in a family of such military components the company intends to put in its pipeline over time.
Solid and highly repeatable performance
The new Anaren couplers feature low insertion loss, excellent phase balance, less amplitude imbalance and high isolation. The new parts are also much less frequency sensitive and feature considerably more power handling capability, as well as a higher maximum operating temperature. In addition, they are available in a lead free version.
The XC0600B-03P 3 dB hybrid coupler operates from 225 to 1000 MHz and features an insertion loss of 0.70 dB maximum, a phase balance of 90° ± 5.0° maximum, an amplitude balance of ± 0.6 dB maximum, a maximum VSWR of 1.33:1 and 17 dB of minimum isolation. The coupler is rated to handle power levels up to 75 W CW. The package dimensions are 0.5 1.0 0.22 inches.
The XC4300-E-03P is also a 3 dB hybrid coupler that operates over the 2500 to 6000 MHz frequency range. This device features a low insertion loss of 0.25 dB maximum, a phase balance of 90° ± 4.0° maximum, an amplitude balance of ±0.75 dB maximum, a maximum VSWR of 1.3:1 and 21 dB of minimum isolation. The coupler is rated to handle power levels up to 100 W CW. The package dimensions are 0.20 0.56 0.089 inches.
The third device in the new family is the XC4300-A-20P. This 20 dB directional coupler also operates over the 2500 to 6000 MHz frequency range with a low insertion loss of 0.2 dB maximum, a mean coupling of ±1.0 dB maximum, a maximum VSWR of 1.3:1 and 18 dB of minimum directivity. The coupler is rated to handle power levels up to 100 W CW.
These three new Anaren Xinger-brand packaged couplers bring high performance and reliability to military broadband applications reducing the cost, parts count and foot print for many demanding applications.
