SMA Cable

Description

This SMA cable is assembled with SMA connector with RJ178, RJ174 etc. cables. It could be connected from SMA to SMA, or SMA to SMB, or SMA to IPEX or other connectors.

Material

SMA Body: GOLD PL.0.8μ"MIN. OVER NICKEL PL.100μ" MIN. THICK OVER COPPER STRIKE OR CUSTOMER REQUIREMENTS.

Contact pin: GOLD PL.0.8μ"MIN. OVER NICKEL PL.100μ" MIN. THICK OVER COPPER STRIKE OR CUSTOMER REQUIREMENTS.

INSULATION: TEFLON WHICH RESIST HIGH TEMPERATURE

Parameter:

1. Basic electrical parameters

Characteristic impedance: The standard impedance is 50 Ω, ensuring matching of signal transmission and low reflection loss

Frequency range:

Standard SMA: DC to 12.4GHz (semi-rigid cable can reach 18GHz)

High performance version: Some models support 24GHz or 26.5GHz (such as vacuum RF connectors)

2. Signal transmission performance

Insertion loss:

At 6GHz, the loss is ≤ 0.15dB, and in the high-frequency range (such as 18GHz), the loss increases linearly with frequency

Voltage Standing Wave Ratio (VSWR):

Direct connection (flexible cable): VSWR ≤ 1.10+0.002f (f is frequency, unit: GHz)

Straight semi-rigid cable: VSWR ≤ 1.05+0.001f 14.

Bent connection: VSWR ≤ 1.20+0.003f (flexible cable) or 1.10+0.001f (semi-rigid cable)

3. Voltage resistance and insulation performance

Insulation resistance: ≥ 5000M Ω (under standard environment)

Voltage resistance:

Working voltage: maximum 335V rms (effective value)

Breakdown voltage: capable of withstanding 1000V rms (sea level standard)

4. Contact performance and stability

Contact resistance:

Between inner conductors: ≤ 3m Ω 45.

Between external conductors: ≤ 2m Ω 45.

Leakage rate (vacuum environment):<10 ⁻¹² Pa · m ³/s (vacuum sealed model)

5. High frequency application characteristics

Material Design:

The inner conductor is made of gold-plated copper to reduce high-frequency signal loss

External conductor coating (such as silver plating or nickel) enhances corrosion resistance and conductivity

Phase stability: Phase drift caused by temperature changes ≤ 0.05 °/℃ (special design models)
