Millimeter-Wave Frequency Reconfigurable Slot Dipole Array with Packaged RF-MEMS Switches

2009-03-27
This paper presents a frequency reconfigurable slot dipole array operating at millimeter-wave frequency band. Dual frequency operation of the array is achieved by using commercial packaged RF-MEMS switches. RF-MEMS switches located on the dipole arms control the electrical length of the slot and enable dual frequency operation.

Millimeter wave gunn diode oscillators
Lüy, Ülkü; Toker, Canan; Department of Electrical and Electronics Engineering (2007)
This thesis presents the design and implementation of a millimeter-wave Gunn diode oscillator operating at 35 GHz (Ka (R) 26.5-40 GHz Band). The aim of the study is to produce a high frequency, high power signal from a negative resistance device situated in a waveguide cavity by applying a direct current bias. First the physics of Gunn diodes is studied and the requirements that Gunn diode operates within the negative differential resistance region is obtained. Then the best design configuration is selected...
Broadband analogue predistortion using a distortion generator based on two-stage RF mixer topology
Nesimoglu, Tayfun (2018-01-01)
An analogue predistorter using a distortion generator based on a two-stage radio frequency mixer topology is presented. The proposed distortion generator achieves fundamental signal cancellation without using a signal cancellation loop or a resonant circuit, thus it generates an error signal that predominantly consists of unwanted intermodulation distortion (IMD). Measurements are performed using multi-tones, WLAN- and Terrestrial Trunked Radio (TETRA)-modulated signals. Distortion generator provides high l...
Frequency tunable metamaterial designs using near field coupled SRR structures in the terahertz region
Ekmeki, Evren; Strikwerda, Andrew C.; Fan, Kebin; Keiser, George; Zhang, Xin; Sayan, Gönül; Averitt, Richard D. (2011-12-01)
We present frequency tunable metamaterials at terahertz frequencies using broadside-coupled split ring resonators (BC-SRRs). Frequency tuning, arising from changes in near field coupling, is obtained by in-plane displacement between the SRR layers. For electrical excitation, the resonance frequency continuously redshifts as a function of displacement. A maximum frequency shift occurs for displacement of half a unit cell resulting in a shift of 663 GHz (51% of f 0). We discuss the difference in the BC-SRR re...
