The slug is actuated by a rod passing through the short circuit. The rate of change of phase-shift as a function of actuator position is small near the extremes of actuation positions, whereby errors in actuator position do not affect the phase-shift....
A high performance 6-18 GHz 5-bit reflection type phase shifter MMIC is presented. It employs a novel ultra-broad-band circuit design technique utilizing a series/parallel LC circuit for an 180° phase shift over all frequencies. The fabricated phase shifter MMIC with SPDT switch suitable fo...
Afterwards, the phase-shift time and the transferred energy of the BBSLCC circuit are calculated to demonstrate the proposed control strategy details. The relationships between the phase-shift time and other circuit parameters such as the inductance and the capacitance are also analyzed. The ...
Meanwhile, the RC-feedback circuit produces negative impedances and improves insertion losses. The implemented reflection-type phase shifter using Si varactor diodes with a capacitance ratio of 2.5:1 and SiGe HBTs with an ft of 25GHz has achieved a maximal relative phase shift of 290. An ...
As an artificial left-handed transmission line, an equivalent high-pass LC circuit realized in a quasi-lumped element technique, has been considered, and the resulting phase shift of such a circuit is given analytically. The obtained measurement results fully confirm the validity of the proposed ...
Topological phase transition in lumped element circuit As a simplified model of our system (see Fig. 1a, b), we begin with a lumped element circuit shown schematically in Fig. 1c. On-node capacitors with a uniform capacitance C establish shunts to a common ground plane. Link inductors with...

In combination with the transformer ratio control, phase shift control (PS) will be utilized. The phase shift angle factor (φ), ranging from 0 to 180°, varies the output voltage of the inverter applied to the resonant circuit using the following expression: 𝑉𝑎𝑏(𝜑)=22−−√...
These are used to keep the pin at logic HIGH or logic LOW when it is not being actively driven by external circuity. Normally these resistors are used with pushbuttons & switches. The pinMode function with INPUT_PULLUP or INPUT_PULLDOWN must be used to configure these pins to input ...
