A T-Shaped Wide-Slot Harmonic Suppression Antenna

IEEE Antennas and Wireless Propagation Letters, 2007
This paper proposes a T-shaped wide-slot harmonic suppression antenna at 4 GHz. Harmonic suppression is achieved by using a narrow microstrip-line-fed and a grounded T-shaped conductor line.

The harmonic suppression of LNA

2008 8th International Symposium on Antennas, Propagation and EM Theory, 2008
In this paper, we designed an amplifier based on the transistor ATF 34143 from Agilent. Networks of input and output with appropriate I/O matching were designed through the ADS design software in order to match the impedance of input and output to 50 Ohm. In addition, special optimizations on noise figure and transmission gain were conducted.

The Harmonic Suppression of DFIG

Advanced Materials Research, 2014
As a result of using converter and the other power electronic devices on the side of doubly-fed induction generator (DFIG) rotor, it will produce a large amount of harmonic current at runtime. In order to reduce the harmonic pollution to power network, DFIG uses a variety of harmonic suppression measures.

Rectangular Waveform Generation with Harmonics Suppression

2016 IEEE 25th Asian Test Symposium (ATS), 2016
This paper proposes signal generator (BIST/BOST) algorithms and architectures for mixed-signal IC testing input. They can provide rectangular waveforms approximated to single-tone and/or two-tone signals with harmonics/IMD suppression. Their circuit consists of digital circuit, a 1-bit DA converter with an analog filter.

Miniaturized rat‐race coupler with harmonic suppression

Microwave and Optical Technology Letters, 2014
ABSTRACTThis article presents a miniaturized rat‐race coupler with harmonic suppression. The proposed coupler only takes 15.1% of the area of the corresponding conventional rat‐race coupler. By replacing the traditional transmission line with the proposed stub‐loaded transmission line equivalently, the coupler performances can be retained and size can ...
