In this article, we report on the successful demonstration of lead zirconate titanate (PZT) thin film based MEMS devices for use in radio frequency (RF) systems. Individual series switches and single pole multi-throw switching elements operating at or below 10 V have been developed capable of operating over a wide temperature range. The switch technology also provides an enabling technology for...

In this paper, a new topology for high-power single-pole-double-throw (SPDT) antenna switch is presented, and its loss mechanisms are fully analyzed. The differential architecture employed in the proposed implementation to prevent unwanted channel formations of OFF-state Rx transistors by relieving voltage swing over devices. addition that, load impedance seen Tx stepped down reduce even more, ...

In this paper, we propose a paper-based pattern switchable antenna system using inkjet-printing technology for bi-direction sensor applications. The proposed antenna system is composed of two directional bow-tie antennas and a switching network. The switching network consists of a single-pole-double-throw (SPDT) switch and a balun element. A double-sided parallel-strip line (DSPSL) is employed ...

Single-pole double-throw (SPDT) switches are a key building block for enabling transceiver time-division duplexing (TDD) when operated as a T/R switch or for eliminating imager fluctuations when operated as a Dicke switch. To provide acceptable compromises of NF, Pout and sensitivity in transceivers or imagers, the switches are required to feature an insertion loss of ~3dB and an isolation of ~...

In this paper, we report a new push-pull-type SPDT (single pole double throw) switch actuated by the combination of electromagnetic and electrostatic forces for low power and low voltage operation. The switch is initially actuated by large electromagnetic force to change its state and is held to maintain its state by applying electrostatic force to reduce static power consumption. The electroma...
