We developed high-speed III-V devices for millimeter-wave receiver applications as InP-based high electron mobility transistors (HEMTs) that had a cavity structure and zero-bias GaAsSb-based heterojunction backward diodes. A high cutoff frequency (fT) of 517 GHz and minimum noise figure (NFmin) of 0.71 dB at 94 GHz were achieved for the InP-based HEMTs, even after the passivation process, by adopting the cavity structure. Since GaAsSb-based diodes that are based on p+-GaAsSb/i-InAlAs/n-InGaAs are mostly lattice-matched to InP, they can be easily integrated with InP-based low-noise amplifiers (LNAs). They indicated a sensitivity of 20,400 V/W at 94 GHz. By integrating the backward diodes with LNAs, highly sensitive receiver MMICs can be fabricated.

In this paper, a three-stage low-noise amplifier (LNA) designed for V-band applications is presented. Each stage of the proposed LNA is the common-source topology with inductive degeneration for minimizing the noise figure (NF). The inductors at the gate and source terminals form a coupling structure which extends the bandwidth with a low NF level. This proposed LNA is implemented in the 90-nm CMOS process technology, which achieves a peak gain of 16.48 dB, a minimum NF of 4.5 dB, and an input PidB of -18.7 dBm. The proposed LNA consumes 17.47 mW power from a 1.2-V voltage supply.

We have developed a cryogenic low noise amplifier (LNA) for phased array antenna. By using this cryogenic LNA, a low noise receiving antenna can be easily available for wireless applications such as radar systems, communication systems, and so on. In this paper, we describe an S-band cryogenic LNA with an RF interfaces having both low loss characteristic and thermal isolation characteristic. The RF interface is realized by coupling resonators with vacuum gap of 1 mm and also has narrow band characteristic. The noise temperature of the cryogenic LNA at 77 K was improved to less than 1/5 as compared with the noise temperature of the same LNA at room temperature.

The proposed phase shifter achieves a 6-bit resolution and a measured root mean square phase error of less than 2.3°, while the maximal insertion loss flatness is ±1.4dB. For all 64 states, the insertion loss is -20dB±3dB including pad loss over 57-66GHz. To the best of our knowledge, this is the first reported 6-bit 60GHz phase shifter in CMOS technology.

It has been reported that the SR (synchrotron radiation) etching process is useful to construct PTFE-based microstructures. This paper treats a trial fabrication of the PTFE-based E-plane waveguide coupler for short millimeter-wave based on the SR etching process of PTFE, with the aim of developing integrated waveguide circuits. First, a cavity-type 3-dB directional coupler is designed at 180 GHz. In this paper, an integrated PTFE pattern, in which the two 3-dB couplers and the matching section are cascaded, is fabricated. Then, the frequency characteristics of the PTFE-based E-plane waveguide coupler are measured, and the validity of the fabrication process is verified.

Microwave wireless power transmission systems require a high RF-DC conversion efficiency rectifier at input power such as 1 W. To meet this requirement, a rectifying device with high breakdown voltage is developed. This paper describes a fabricated high breakdown voltage GaAs Schottky Barrier Diode (SBD) as the rectifying device. The fabricated GaAs SBD at low doping concentration of 2.6×1016 cm-3 achieves breakdown voltage of 23.5 V and the conversion efficiency of 77.2% at input power of 27 dBm under condition without harmonic tuning technique which is agreed with simulation result. When harmonic tuning technique is adopted, a 5.8 GHz-band singleshunt rectifier with the fabricated GaAs SBD achieves the conversion efficiency of 81.7% at input power of 27 dBm in simulation. This conversion efficiency is the best performance at around 1 W input power and C-band to our knowledge.
