Low Loss LDPTFE Phase Stable Cable UniFlex ULE147A

Overview

A phase stable coaxial cable is a high-performance RF cable designed to minimize phase variation under changing environmental and mechanical conditions. Unlike standard coaxial cables, which can exhibit significant phase drift when exposed to temperature fluctuations, bending, or flexing, phase stable cables maintain consistent electrical length and performance, ensuring reliable signal integrity in demanding applications.

Features

• Phase Stability: Engineered to reduce phase shift caused by temperature changes, flexure, or mechanical stress.

• Frequency Range: Available in versions supporting DC up to 110 GHz and beyond, depending on design.

• Construction: Uses low-loss dielectric materials (e.g., PTFE variants, expanded PTFE, or proprietary composites) and precision manufacturing for minimal variation.

• Flexibility & Durability: Designed for repeated flexing, suitable for lab test environments, production testing, and field use.

• Connector Options: Compatible with precision RF connectors such as SMA, 2.92 mm, 2.4 mm, 1.85 mm,1.0 mm and others.

Applications

• Vector network analyzer (VNA) measurements

• Automated test equipment (ATE)

• High-frequency device characterization

• Aerospace, defense, and satellite communication systems

• TV and radio transmission systems

• studio equipment, satellite uplink/downlink stations

• RF/microwave test benches and calibration equipment

FAQ

Sample Delivery Time

Regular models require 15 days, while some complex connectors require 25 days.

Sample Fee

Most RF connectors are CNC-machined parts and do not require mold-making.

However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.

This fee will be refunded after a 5K bulk order.

Guarantee

Brass RF connectors come with a one-year warranty.

Stainless steel connectors come with a three-year warranty.

The lifespan also depends on the contact material  beryllium contacts offer better durability.

Are RF connectors weatherproof?

Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.

What’s the difference between male and female RF connectors?

Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.

What is VSWR, and why does it matter?

VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.

What are typical applications of RF connectors?

Telecom (5G, LTE, satellite) Aerospace & defense (radar, avionics, secure comms) Test & measurement (network/spectrum analyzers) Broadcast & video distribution Automotive radar and IoT devices Medical imaging & equipment
