An Ultra‐Wideband Low Noise Colpitts VCO Using SiGe Bi‐CMOS Technology

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
This paper proposes a wideband voltage‐controlled oscillator (VCO) circuit based on the Colpitts oscillator structure. By employing amplifiers, frequency multipliers, and other techniques to process the output signal, an ultra‐wideband frequency tuning range can be achieved.

A K‐band eight‐element reconfigurable phased‐array receiver with high Tx‐band rejection

IET Microwaves, Antennas &Propagation, Volume 18, Issue 12, Page 869-877, December 2024.
Abstract A K‐band eight‐element phased‐array receiver is proposed, featuring a reconfigurable beam count and high Tx‐band rejection, tailored for satellite communication applications. By precisely designing the inter‐stage and output matching networks of the four‐stage low‐noise amplifier, the Tx‐band rejection of the receiver can be effectively ...

Active quasi circulator: Comprehensive review and performance comparison

Engineering Reports, Volume 6, Issue 6, June 2024.
To cope up with the increased data transmission rate due to the modern multiband wireless communication systems, the three‐port circulator must be equipped with the ability to operate in different frequency levels while having adequate bandwidth. Thus, designing circulator as an antenna interface device becomes a challenging, particularly active‐quasi ...

A compact 60‐GHz on‐chip bandpass filter in GaAs technology

Electronics Letters, Volume 60, Issue 7, April 2024.
A compact 60‐GHz on‐chip bandpass filter (BPF) is presented using gallium arsenide (GaAs) technology. The measurements show that it has a centre frequency of 60.2 GHz with a bandwidth of 14%, and the minimum insertion loss (IL) within the passband is 2.57 dB. The chip size, excluding the feedings, is about 0.265 mm × 0.184 mm. Abstract A compact 60‐GHz

Modulation Bandwidth Investigation of Voltage-Controlled Oscillators Under Periodic Linear Frequency Modulation

IEEE Open Journal of Circuits and Systems
The modulation bandwidth of a voltage-controlled oscillator (VCO) is a key design metric that defines its ability to respond to fast tuning voltages and change its frequency accordingly. While prior works have addressed practical methods for measuring it,

Survey of Connectivity Restoration in 3D Wireless Ad Hoc/Sensor Networks

International Journal of Distributed Sensor Networks, Volume 2024, Issue 1, 2024.
Wireless ad hoc/sensor networks (WASN) have seen increased application in three‐dimensional (3D) environments, such as underwater and aerial scenarios. However, WASN may be fragmented or unable to connect continuously due to the harsh surrounding environment or high mobility.
