Difficulty: Easy
Correct Answer: False
Explanation:
Introduction / Context:SWR (standing-wave ratio) is a measure of mismatch between a connector (or any component) and the system impedance. In microwave engineering, mismatch leads to reflections, ripple in passbands, and wasted power.
Given Data / Assumptions:
Concept / Approach:
Lower SWR corresponds to lower reflection coefficient |Γ| and higher return loss. A well-designed connector aims for SWR close to 1.0 over its specified band. High SWR indicates substantial mismatch, causing ripple, distortion, and heating.
Step-by-Step Solution:
1) Recall: SWR = (1 + |Γ|) / (1 − |Γ|); SWR = 1 means perfect match.2) Good connectors advertise low VSWR (e.g., ≤ 1.15 or ≤ 1.2) across the band.3) Therefore, the statement “a microwave connector should have high SWR” is false.Verification / Alternative check:
Datasheets list return loss and VSWR targets; better-grade connectors have higher return loss (e.g., > 20 dB) meaning lower SWR.
Why Other Options Are Wrong:
Any conditional “True” variants contradict basic impedance-matching practice; performance expectations do not reverse at short lengths or high frequencies.
Common Pitfalls:
Confusing “high return loss” (good) with “high SWR” (bad). Return loss high = reflections small; SWR high = reflections large.
Final Answer:
False
