“…Optimizing the fabrication process [5] is always helpful, yet it is a costly investment and perfection is never reached, therefore, an effort on the design part is unavoidable. Use of resistors can be completely abandoned [6], but the resulting bandwidth is narrow. In this brief, we analyze the effect of nonideal resistors in couplers and dividers, and propose accurate isolation networks which cancel the resistor parasitic effects and are also tolerant to systematic errors in the resistance values.…”

When quadrature couplers and power dividers are implemented in integrated circuits, accurate isolation networks can not be realized due to the nonideal resistors and the process variations. We present an isolation network design technique which cancels the resistor parasitic effects and also increases the tolerance to variations in the resistance values. A Lange coupler and a power divider are designed at Ka-band using the proposed accurate and process-tolerant isolation networks. The improvement is analytically shown and empirically verified with our in-house GaN-based microstrip MMIC process. For the coupler, the measured return losses and isolation are better than 20 dB from DC to 40 GHz. The power divider achieves 20 dB return losses and isolation in a fractional bandwidth of 50%. Both devices maintain 20 dB performance even when the variation in sheet resistance is as high as 30%.

“…Several approaches have been incorporated to design different power dividers with different specifications. [1][2][3][4][5][6][7] Wilkinson, 8 Gysel, [9][10][11] and Bagley power divider 12,13 are examples of such dividers that are widely used in RF circuits and microwave systems. Conventional equal-split Bagley power divider (BPD) which contains odd number of output ports has been presented in Reference 14.…”

An exact design for seven-way Bagley power divider (7-way BPD) is introduced. The objective of this article is to derive general closed-form expressions for the impedances between adjacent ports for unequal-split 7-way BPD. The values of the impedances control the output power ratio. Full derivation of S-parameters followed by exact impedance equations will be presented. A parametric study in addition to several examples will be given to validate the proposed derivation
