In this paper, a new matrix-based approach for differential noise figure measurement will be presented. Passive components used for embedding a differential device into a single ended test setup are characterized by their noise correlation matrices. Then, signal transfer via the component chain is described by chain matrices. Determining the output referred noise correlation matrix of the device under test this way, a noise figure can be denoted.

In this paper, a 220 GHz solid-state power amplifier (SSPA) module is presented. Eight-way on-chip power combining is used to achieve a saturated output power ≥ 50 mW over a 217.5 to 220 GHz bandwidth, representing a significant increase in SSPA output power at this frequency compared to prior state of the art. The amplifier MMIC is implemented in coplanar waveguide (CPW) technology and uses sub 50 nm InP HEMT transistors. Two levels of power combining, a 2∶1 tandem coupler and a 4∶1 Dolph-Chebychev transformer, are realized in CPW. The module demonstrates ≥ 11.5 dB small signal gain from 207 to 230 GHz. Saturated output power ≥ 40 mW was measured from 216 to 222.5 GHz.

This paper will review the state-of-the-art for modeling compound semiconductor HFETs and HEMTs for microwave power applications. Some simple physics shows why SPICE models, or compact models, cannot contain all aspects of the device operation. Because the models are incomplete, any given model may always be improved and thus, modifiable user-defined compact models are preferred. In particular, Verilog-A coded models are shown to have many desirable features. Minimum modeling requirements for accurate system and circuit simulation are described, as well as present modeling techniques.

A 14.5 GHz Injection Locked Oscillator (ILO) with digital output phase control has been implemented in a 90 nm CMOS process. It is intended for LO signal generation in integrated phased array transceivers. The chip, measuring 360×530 µm2 including pads, was characterized using on-wafer probing. It has a 1.4 GHz frequency range where full 3600 phase range is achieved with 3rd order subharmonic mixers. The free running phase noise is −105 dBc/Hz at 1 MHz offset. It consumes 9.4 mA from a 1.2 V supply.

This paper shows the ability of an all analogue Retrodirective Radar, the first of its type, to provide continuous surveillance and near instantaneous target acquisition while automatically beam steering in real time onto a target which is presented to it. Assessment of the phase conjugation unit shows that the Radar is capable of operating either in CW or in pulsed mode. Test results are presented which show that Retrodirective tracking of targets travelling at speeds in excess of 780 m/s is possible. To confirm tracking ability bistatic results of a small near field target are presented, and the capability is also shown to extract the position of the near field target with only very simple calculations, with no DSP circuitry required.

We enhance a tuning space mapping algorithm through a response correction. We demonstrate that the response corrected tuning model can serve as a high-performance surrogate for fast yield estimation and design centering. We illustrate yield analysis of a second-order tapped-line microstrip filter using our model. We perform yield-driven design on a double-ring filter example and verify the design with the EM model.

This paper describes a 120-GHz-band quadrature phase shift keying (QPSK) modulator and demodulator fabricated on microwave monolithic integrated circuits (MMICs) for a 10-Gbit/s wireless link. The MMICs were fabricated using 0.1-µm-gate InP HEMTs and coplanar waveguides. The direct-conversion modulator consists of hybrid couplers, gain-control amplifiers, and combiners. The delay demodulator has a 200-ps delay line, distribution amplifiers, a voltage-controlled phase shifter, and detectors. The modulator and demodulator MMICs were mounted in WR-8 waveguide modules to evaluate the characteristics of 10-Gbit/s transmission. The bit error rate (BER) for 10-Gbit/s pseudorandom binary sequence (PRBS) 27–1 data was smaller than 10−10.

We describe our recent achievements in the integration of narrowband photonic RF receivers and discuss their ultimate performance parameters. The best sensitivity and the spurious free dynamic range achieved in the current built of our coherent receiver approaches −145 dBm/Hz and 90 dB/Hz2/3 respectively. We plan to improve these values to −164 dBm/Hz and 105 dB/Hz2/3 in the next generation receivers, while keeping the 13.5×8.5×4.7 mm form factor intact.

A fully integrated power amplifier operating at switching and linear mode is implemented using 0.18-µm CMOS technology. To maximize performance for both operation modes, the fundamental load impedances are optimized with a variable capacitor for GSM and EDGE application. For GSM application, 32 dBm of the output power with 45 % of the drain efficiency is achieved at 1.76 GHz. With EDGE modulation signal at 1.76 GHz, error vector magnitude (EVM) has an RMS value of less than 5 % up to 27.5 dBm of the output power, and 28.1 % of modulated PAE is achieved at this power. The output spectrum is confined within the inside of mask up to 27.5 dBm of the output power.
