Balancer CMRR
Suppression ratio is the total of coaxial line, change the coaxial line because of the access locations will be different results. In addition, the results also,[link widoczny dla zalogowanych], and half-wave oscillator is directly connected with the coaxial line is similar. 4X / 4 choke common set of type balancer suppression than 4.1 and the equivalent circuit diagram of the left loop 4 for Il, the right loop for the I2, from right loop that I2 = I1 / 3. I1 = v / (Zo +2 Zo / 3 + jZotanil [.),. *. , 2 = v / (szo + j3ZotgpL) ZoV Kids in Figure 4zoz0 Jian zo = v / (5 + j3tgilL), and maximum V / 2,[link widoczny dla zalogowanych], compared, CMRR = 20log (2.5 + j1.5tgflL) dB. 4.2 The calculated and measured values of calculated and measured discussion of Figure 54.3 the curve compared to the same shape, indicating that the algorithm is feasible; but appears inconsistent with the frequency of the maximum inhibition point may be calculated without taking account of VI on the capacitor margin due. Antenna wire 18 and the wound of 5 results balancer 5.1 Single-lane and around a 10-2O'3O mO black-5O5.2 dual two-lane and winding (and parallel) mO-10 .2 O3OO-5o Figure 65.3 pairs and groups around the double (and series) dBO a 3OO a 10-2O 5O Figure 7 Figure 8 one or more of the four holes in the cores within the cable and around the two laps with a two-( shown) the results obtained, and the parallel or dual two-lane and series are better than total suppression,[link widoczny dla zalogowanych], and around two-lane single group, but that far, a total of about 20dB than suppressing nearby. Two holes around the core wire and four rounds is the most commonly used, the test results and downs larger, four-hole twice as smooth. 6X/2U ring balancer of the total suppression than 6.1 equivalent circuit by three contacts ΣI: 0, three equations can be out by the transmission line can be out two-equation: l / Zo + (l-2) / Z0 +, l = 0 antenna technology first 18 ~ 31 ~ Figure 96.2 calculation and test results (V2 a V3) / Zo-jr2 = 0 (V3 A V) / Z0 + (V3 a V1) / Z0 + (V3 a V2) / Z0 = 0V1 = V2cosflL + jI2ZosinflLI1 = 12cosflL + J (V2/Zo) sinflL simultaneous five-style, with the determinant method, can solve: V = Figure 1O calculated and measured curves compared to the same shape, indicating that the algorithm is feasible ; but appears inconsistent with the frequency of the maximum inhibition point, the length may be measured accurately. 7 single symmetrical cross-section of single balancer balancer symmetrical cross sectional shape, there are three: (.) Gap for the coaxial type, loJ of plate-wire. . . Three pole, their effectiveness will balance the same? To this end a total suppression ratio measurement, measured as follows: slot-type than in the total suppression over 30dB, 20dB line around boards, three pole at about 12dB . Sophisticated gap-type used to compare the occasion, the board line for high-power, and the three rod can only be used not care about the occasion. 8, the jumper wire balancer of symmetrical 8.1 points from the input common-mode power of a 32-a (V1 A V) / Z + (V1 a V3) / z0 + V1/jz0tgflL = 0 (V2 a V1) / z + (V2 a V3) / z0 + V2/jz0tgflL = 0 antennas 18 (a V1) / Zo + (v3 a V2) / Zo + (v3 a v) / Zo = 0 three-node line equation, with the determinant Solving equations, the denominator D the same, just look at molecules (derivation omitted): V1VYYo (2Y + Yo-jYctgflL) / D = because V1 =, so the poor end of no output. Figure 8.2 by the differential-ended input l3 (V1 A-v2) / (Zo + jx) +1 / jz0tgflL + (1 a 3) / Zo: 0 (+-V1) / (Zo +) + V2/jZotgflL + (2 a ) / Z0: 0v3/Zo + (v3 a V1) / Zo + (v3 a) / Z0 = 0 can be solved v3 30 by the ratio of the total suppression results derived show that the total two-symmetric suppression ratio and balancer jumper has nothing to do, jumper only affects the match does not affect the balance. Practice has proved that, plus the core of the double symmetric bandwidth balancer done more than 1000:1. The total suppression than 40dB or more. 9 Conclusion on the circuit CMRR Introduction balancer used up, the balancer of the evaluation of the introduction of a multi-parameter method is more simple than the other two,[link widoczny dla zalogowanych], but also more acceptable to some. Measurements were introduced after the suppression ratio, making the slot-type,[link widoczny dla zalogowanych], plate wire rod and the balance of the effectiveness of the three at a glance. Derivation of the introduction of a total suppression than after the jumper had to admit did not affect the balance. Antenna 18 of a 33 -
