Anritsu Company introduces a family of Integrated V Connectors® utilizing a design that incorporates the launcher and integrated glass bead in a single housing to produce significant improvements in efficiency and performance while also reducing design and manufacturing costs. Because of this design, the Integrated V Connectors feature excellent return loss and SWR so they are extremely well suited for use as the RF input in 40 Gpbs optical modulators, especially those systems that use the NRZ modulation format where greater bandwidth is required to minimize signal degradation. They can also be used in traditional microwave applications where specified connector performance at frequencies up to 65 GHz is needed.

Two versions of the Integrated V Connector have been developed. The V115F is a ground lip version, which includes all compensation steps for matching to Microstrip or Coplanar Waveguide (CPW). It provides a very short ground path to help maintain good VSWR at millimeter wave frequencies. A screw-in version, the V116F, is also available. Both Integrated V Connectors are fully compatible with existing V Connectors, as well as with 2.4 mm connectors.

A number of advantages are realized by including the ground lip as part of the connector. First, it provides a simple way for the current designer to achieve a very low impedance, broadband, ground connection right at the connector for improved performance. This is evident by the integrated V connector's industry-best return loss of 15 dB over the frequency range of DC to 65 GHz, with typical SWR of 1.3:1 at 65 GHz.

Installation is also made much easier by having the launcher and glass bead in a single housing. The V115F can be easily soldered into the housing wall using SN62 solder. The V116F is screwed in and secured using torque. If a hermetic seal is required, the V116F can also be soldered.
