Description

Impedance matching: What impedance is the BNC male side and what is the banana side? (e.g., 50 Ω → 75 Ω, or 50 Ω → 50 Ω, etc) Frequency range / bandwidth: Up to what frequency (MHz or GHz) is the balun specified? Does performance degrade at higher frequencies? Insertion loss (in dB) across the operational band. Return loss / VSWR across the band. Connector details: BNC male: type, chassis/panel or cable mount Banana posts: size (4 mm banana? Binding posts?), colour coding (Red/Black), polarity orientation Power/pulse handling: Max voltage, current or RF power (if used at RF) or current rating (if audio) Mechanical / environmental: Dimensions, weight, temperature range, humidity, mounting / chassis vs inline
