This paper presents a novel automatic attenuator with ultra-fast transient response time. The proposed automatic attenuator combines control generation and a digital attenuator together. The control generation chain consists of a RF envelope detector, voltage comparators and a logic circuit. The state of the digital attenuator is determined by the output control signals of the control generation chain. The chip is fabricated using HuaHong 0.18um standard CMOS technology. Measured results are offered showing that the transient response time of the whole system is less than 10 ns in the ultra-wide operation frequency range of 1GHz~10GHz.

“…The T/R (transmit/receive) switch is a component of crucial importance in space applications for the accuracy of the phase and amplitude control in combination with the maximum dynamic range. Many efforts have been put forward to design SPDT (Single-Pole Double-Throw) switch circuits operating from UHF band to mid Ku band [2], [3]. In order to make the switch radiation-tolerant, firstly we present here a novel SPDT annular MOSFET switch design at 15-GHz in IBM SiGe BiCMOS 7HP process.…”

A high isolation 15-GHz radiation tolerant SPDT (Single-Pole Double-Throw) annular MOSFET switch, for space application, was designed and integrated in a SiGe BiCMOS process. Schwartz-Christoffel transformation, based on conformal mapping, and parasitic capacitance extraction methods were utilized to derive the equivalent circuit model of the octagonal annular MOSFET, which has demonstrated improved total-dose radiation tolerance in CMOS circuits. The designed switch achieves 40.5-dB isolation at 15-GHz.

“…Recently, especially for space applications, radiation-tolerant and a highly integrated SiGe BiCMOS technology has emerged as a low-cost alternative solution. Various SiGe pin diode switches have been developed in the past [2][3][4]. In [2], a top side polyimide process has been used to implement the transmission line to reduce the insertion loss of the switch.…”

A comparison of insertion loss between a conventional clockwise and a proposed counter-clockwise SiGe pin diode SPDT switch based on an analysis of parasitic effects is presented. In a silicon-based process, the counterclockwise switch is analytically demonstrated to have lower insertion loss than the clockwise switch owing to the alleviation of parasitic effects. Measurement data show good agreement with the presented analysis.
