Abstract Next generation of RF sensor modules, mainly for airborne applications, will cover a variety of multifunction in terms of different operating modes, e.g. Radar, EW and Communications / Datalinks. The operating frequencies will cover a bandwidth of &gt; 10 GHz and for realisation of modern Active Electronically Steered Antennas (AESA) the Transmit/Receive (T/R) modules have to match with challenging geometry demands, and RF requirements, like switching and filtering between different operational frequencies in transmit and receive mode. New GaN technology based MMICs, e.g. LNA, HPA are in development and multifunctional components (MFC MMICs) cover more than one RF function in one chip. Different front end demonstrators will be presented, based on multilayer ceramic (LTCC) and RF-PCB and associated assembly technologies, like chip&wire and SMD reflow soldering. These TRM front ends include a Low Noise Amplifier with an integrated Switch (LNA/SW) and for characterisation the measured Noise Figure (NF), a key characteristic for receive performance, will be compared. The need for high integration on module level is obvious and therefore specific demands for low loss ceramic and PCB based modules, packages and housings exist.

This paper presents the design and analysis of a continuously tunable low noise amplifier (LNA) with an operating frequency from 2.2 GHz to 2.8 GHz. Continuous tuning is achieved through a radio frequency impedance transformer network in the input matching stage. The proposed circuit consists of four stages, namely transformer stage, tuning stage, phase shifter and gain stage. Frequency tuning is controlled by varying output current through bias voltage of tuning stage. The circuit includes an active phase shifter in the feedback path of amplifier to shift the phase of the amplified signal. Phase shift is required to further achieve tunability through transformer. The LNA achieves a maximum simulated gain of 18 dB. The LNA attains a perfect impedance match across the tuning range with stable operation. In addition, it achieves a minimum noise figure of 1.4 dB.

In this paper a GaN-on-Si MMIC Low-Noise Amplifier (LNA) working in the Ka-band is shown. The chosen technology for the design is a 100 nm gate length HEMT provided by OMMIC foundry. Both small-signal and noise models had been previously extracted by the means of an extensive measurement campaign, and were then employed in the design of the presented LNA. The amplifier presents an average noise figure of 2.4 dB, a 30 dB average gain value, and input/output matching higher than 10 dB in the whole 34–37.5 Ghz design band, while non-linear measurements testify a minimum output 1 dB compression point of 23 dBm in the specific 35–36.5 GHz target band. This shows the suitability of the chosen technology for low-noise applications.
