Balun input impedance
웹As the balun input impedance Z,=8.33 ohms, each of the input transmission lines 10 and 12 must provide a load of 2,, =1 6.66 ohms, such that the parallel combination is 8.33 ohms. At the balun output, the series connected transmission lines 10 and 12 must add up to 50 ohms; thus, each line must be terminated in Z =25 ohms. 웹2024년 2월 12일 · Furthermore, input matching of the balun is also of importance: The balun input should be well matched to the characteristic impedance of the antenna for optimal results. To observe the input matching of the balun, a simulation setup similar to that of Fig. 5 is developed; the primary winding is connected to a single-ended \(75\varOmega\) port to …

웹This paper presents a low-noise amplifier (LNA) with single to differential conversion (Balun) for multi-standard radio applications. The proposed LNA combines a common-gate (CG) stage for wideband input matching and a common-source (CS) stage to cancel the noise and distortion of the CG stage. Using the proposed technique, a low noise figure (NF) is … 웹2024년 10월 22일 · Hello everyone! we are using AD9371 eva board, after giving input -5dBm to its input RX1 the overall impedance of the RX1 is out now. i know the max input should be -14 dBm but i gave -5dBm because AGCs were working fine. i am using Network analyzer to check the impedance RX2 is 50-52 ohms but RX1 is 120-140 ohms, i have replaced the …
