In the presence of a strong received signal, non-linear radio frequency (RF) front-end components generate distortion products that add interference to a wanted signal. In this paper, an interference suppression technique using frequency retranslation is presented. When the wanted signal level is high, experimental results show a suppression of intermodulation distortion (IMD) by 25 dB. When a small wanted signal is received along with high level interferers, the technique suppresses interferers by 14 dB and in-band interference by more than 18 dB.

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 microstrip patch antenna using RF MEMS technology
Erdıl, Emre; Topallı, Kagan; Unlu, Mehmet; Aydın Çivi, Hatice Özlem; Akın, Tayfun (2007-04-01)
A novel reconfigurable microstrip patch antenna is presented that is monolithically integrated with RF microelectromechanical systems (MEMS) capacitors for tuning the resonant frequency. Reconfigurability of the operating frequency of the microstrip patch antenna is achieved by loading it with a coplanar waveguide (CPW) stub on which variable MEMS capacitors are placed periodically. MEMS capacitors are implemented with surface micromachining technology, where a 1-mu m thick aluminum structural layer is plac...
Simultaneous phase and amplitude control using triple stub topology and its implementation using rf mems technology
Demir, Şimşek; Akın, Tayfun (United States Patent and Trademark Office, 2009-9-15)
This invention relates to techniques for controlling the amplitude and the insertion phase of an input signal in RF applications. More particularly, this invention relates to phase shifters, vector modulators, and attenuators employing both semi-conductor and RF microelectromechanical systems (MEMS) technologies.

Thin-Film PZT based Multi-Channel Acoustic MEMS Transducer for Cochlear Implant Applications
Yüksel, Muhammed Berat; Külah, Haluk (2021-01-01)
AuthorThis paper presents a multi-channel acoustic transducer that works within the audible frequency range (250-5500 Hz) and mimics the operation of the cochlea by filtering incoming sound. The transducer is composed of eight thin film piezoelectric cantilever beams with different resonance frequencies. The transducer is well suited to be implanted in middle ear cavity with an active volume of 5 mm × 5 mm × 0.62 mm and mass of 4.8 mg. Resonance frequencies and piezoelectric outputs of the bea...
