Coaxial cable assembly suitable for fixed wiring inside and between equipment used in the microwave band up to 100GHz (continuous operating temperature range: -30 to +85°C).
These cables have excellent formability (shape-retention capability) that make wiring work easy and exhibit superior loss characteristics compared to semi-rigid cables.
Standard connectors are SMA (m) straight connectors, although other connectors can be used as required.

Features

– Excellent formability.
– The 4 Series achieves lower insertion loss than semi-rigid cables with the same outer cable diameter.
– The 5 Series achieves lower insertion loss than semi-flexible cables with the same outer cable diameter.
– Can be bent around 5 times with no property changes.

Use

– Fixed wiring for communication equipment on base stations.
– Fixed wiring for research and development boards.

Junkosha’s metrology-grade cable exhibits excellent phase (within +/- 4.5˚ at 50GHz) and amplitude (within +/- 0.08dB at 50GHz) stability in flexure alongside strong phase stability in temperature. The cable is flexible and can maintain this level of performance when bent 180˚ on a 2.25” radius mandrel, with no spring back. Able to reach 50GHz and available in a 2.4mm connector, the assembly also displays impressive performance durability – 50,000 tick tock cycles is typical. The ruggedized port side NMD connector is also available to ensure reliable connections to the Vector Network Analyzer (VNA).

Features

– The highest precision
– Guaranteed Phase & Amplitude stability
– Ruggedized NMD connectors available

Use

– Vector network analyzers
– Calibration
– The highest accuracy measurement
