Phase matching is a term generally used to describe two or more cable assemblies with ideally the same electrical length. Nowadays the microwave systems are in increased need for phase matched coaxial cable assemblies.
Typical applications can be found in:
- Phased Array Radars
- Multi-Beam Antenna Arrays
- Multi-Channel Amplifiers
- Environmental, Production or Lab Testing etc
Normally two specifications are used for phase matched cables assemblies:
1. Time Delay Match
Measure the time delay of each cable assembly by VNA, mark the time delay data typically at the middle point of the frequency range.
For example, a pair of 4 pcs cable assembly matched as DC-67GHz, time delay +/-2ps. Typical phase matching data from RF ONE are shown in below table.
2. Electrical Length Match in Degrees at a Specified Frequency
Measure the phase of each cable assembly by VNA across the required frequency range.
For example, a pair of 4 pcs cable assembly matched as DC-26.5GHz, +/-5 degree. Typical phase matching data from RF ONE are in below table.
Thanks to our precisely controlled cable manufacturing process and highly skilled & experienced technicians, RF ONE is able to offer phase matched cable assemblies up to 110 GHz matched in a pair, or in a set to meet tolerance such as +/- 2ps to 67 GHz or +/-4 degree through 18 GHz.
Depending on the application, a variety of cable series available in phase match:
When phase or delay matched cable assemblies are needed, please specify the below requirements:
1) Frequency of operation
2) Required phase match or delay match in ± ps or in ± degree@ x GHz
3) Quantity of cable assemblies in one set which are to be matched
4) Length of cable assemblies
5) Connectors of the assemblies in one set or pair
