We present monolithic microwave integrated circuit (MMIC) frequency converter, which can be used for up and down conversion, due to the large RF and IF port bandwidth. The MMIC converters are based on commercially available GaAs mHEMT technology and are comprised of a Gilbert mixer cell core, baluns and combiners. Single ended and balanced configurations DC and AC coupled have been investigated...

In this letter, the design and measurement of the first SiGe integrated-circuit LNA specifically designed for operation at cryogenic temperatures is presented. At room temperature, the circuit provides greater than 25.8 dB of gain with an average noise temperature of 76 K and of 9 dB for frequencies in the 0.1–5 GHz band. At 15 K, the amplifier has greater than 29.6 dB of gain with an average o...

Lithium niobate on insulator (LNOI) has been demonstrated as a promising platform for photonic integrated circuits (PICs), thanks to its excellent properties such strong electro-optic effect, low material loss, and wide transparency window. Herein, monolithic PIC high-speed data communication application lithium-niobate-etchless with silicon nitride (Si3N4) loading is proposed demonstrated. The...

Abstract : Microstrip antennas or patch antennas are popular for their attractive features such as low profile, low weight, low cost, ease of fabrication and integration with RF devices. Micro strip antennas have been found favorable because they are inexpensive to manufacture and compatible with monolithic microwave integrated circuit designs (MMIC). They are usually employed at UHF and higher...

Abstract The concept, state of the art, and future development directions of hybrid semiconductor integrated circuits (HySICs), which combine RF-CMOS ICs with compound semiconductor monolithic microwave integrated circuits (MMICs) are described in this paper, taking up recent wireless technologies as example applications. It is shown that ICs with superior function can be designed by mixing the...

In this paper, a novel approach has been suggested to obtain an improved spurious-free window for dielectric resonator in microwave integrated circuit environment. In microwave integrated circuit environment, the dielectric resonator placed on a thin dielectric substrate gets located asymmetrically with respect to its shielding enclosure. A reduced separation in frequencies (mode separation) is...

This thesis addresses integrated circuit component, packaging, and microwave design for both AC and DC Josephson voltage standard (JVS) systems. The components developed in this work combine techniques from both the distributed and lumped-element microwave design in the frequency range 0–40 GHz. The National Institute of Standards and Technology (NIST) JVS systems rely on 10 000 to 300 000 micr...

A single-chip dual-band power amplifier monolithic microwave integrated circuit (MMIC) operating at 3.5V single supply has been developed for both WLAN 2.4GHz and 5.2GHz with IEEE 802.11b/g/a standards applications. The MMIC utilizes the process of WINs Corp. with an InGaP/GaAs HBT process. The dual-band power amplifier constructed based on the design of adaptive RF bias choke circuits and prop...

The strategies to increase the functionality of an integrated circuit or system by the integration of new components as an adequate scaling level is well known as the “Morethan-Moore” strategy in the semiconductor industry. These “MtM” approaches can be distinguished to monolithic and heterogeneous integration concepts, respectively. The latter one enables in general a high flexibility for the ...
