Description
Introduction
Hualink SMA 4 holes flange RF connector includes a Teflon dielectric, a passivated stainless steel body, and a heavy gold plated beryllium copper. This SMA female 4 holes flange connector is developed for application up to 26.5 GHz and accepting .020 inch pin, it's easy to connect and disconnect on panel, which help customers to upgrade system easily. It's widely used in splitters, combiners, circulators etc. Comparing 2 holes design, 4 holes version provide firmer fixing but will take up more space.

FAQ
1. A measure of how much power is reflected
■ Return Loss: The portion of a signal that is lost due to a reflection of power at a line discontinuity. Return Loss is similar to VSWR and is generally preferred in the CATV industry to a VSWR specification
Return Loss = Ratio of reflected to incident power in dB
■ VSWR: Acronym for Voltage Standing Wave Ratio. VSWR is the ratio of voltage applied to voltage reflected. It is the major factor contributing to the total signal efficiency of the connector.
VSWR = Ratio of maximum to minimum electric field (Voltage)
■ Best performance is achieved when the impedance of the cable and the connector are the same (matched)
2. Insertion Loss
■ Insertion Loss is expressed in dB, and is a measure of the total loss of power going through a device
IL = -20*log (Pout/Pin)
■ Includes losses due to reflection (usually the dominant factor unless the Return Loss is very low <-26 dB), plus losses due to the dielectric and metal conductors (Attenuation)
3. Passive Intermodulation Distortion
■ Spurious Signals created by non-linear mixing of 2 or more frequencies in a passive device
FIM3 = 2* F1-F2
■ dBm: measure of power relative to 1 milliwatt
■ dBc: measure of dB below a specified carrier level
