Spatial power combiner using a planar active transmitarray of stacked patches
An X-band spatial power combiner, which uses a planar transmitarray (TXA) of orthogonally polarized stacked microstrip patches integrated with input and output ports of transistor amplifiers is described.

Matched wideband low-noise amplifiers for radio astronomy [PDF]
Two packaged low noise amplifiers for the 0.3–4 GHz frequency range are described. The amplifiers can be operated at temperatures of 300–4 K and achieve noise temperatures in the 5 K range (

N-Type Printed Organic Source-Gated Transistors with High Intrinsic Gain
Source-gated transistors (SGTs) are emerging devices enabling high-gain single-stage amplifiers with low complexity. To date, the p-type printed organic SGT (OSGT) has been developed and showed high gain and low power consumption.

A correlation noise spectrometer for flicker noise measurement in graphene samples [PDF]
We present a high-resolution digital correlation spectrum analyzer for the measurement of low frequency resistance fluctuations in graphene samples. The system exploits the cross-correlation method to reject the amplifiers' noise.
