В данной работе представлены результаты разработки СВЧ монолитной интегральной схемы шестиразрядного фазовращателя и усилителя мощности диапазона частот 26-30 ГГц. СКО ошибки по фазе и амплитуде фазовращателя составили 1,2 град. и 0,13 дБ соответственно. Максимальная выходная мощность и КПД по добавленной мощности усилителя в точке сжатия Ку на 1 дБ составили 30 дБм и 20 % соответственно. This paper describes the design, layout, and performance of 6-bit phase shifter and power amplifier monolithic microwave integrated circuit (MMIC), 26-30 GHz band. Phase shifter MMIC has RMS phase error of 1.2 deg. And RMD amplitude error is 0.13 dB. MMIC power amplifier has output power capability of 30 dBm at 1 dB gain compression (P-1dB) and PAE of 20 %.

This paper presents a novel method to realize a current mode instrumentation amplifier (CMIA) through CDBA (Current difference Buffered Amplifier). It employs two CDBAs and two resistors to obtain desired functionality. Further, it does not require any resistor matching. The gain can be set according to the resistor values. It offers high differential gain and a bandwidth, which is independent of gain. The working of the circuit is verified through PSPICE simulations using CFOA IC based CDBA realization.
