چکیده

Introduction This application note is focused on exploiting the RF design capabilities of HFA3046/3096/3127/3128 transistor arrays. Detailed design procedures, using these transistor arrays, for a matched (800MHz to 2500MHz) high-gain low-noise amplifier and a 10MHz to 600MHz wideband feedback amplifier are described. The HFA3046, HFA3096, HFA3127, HFA3128 transistor arrays are fabricated in a complementary bipolar bonded wafer silicon-on-insulator (SOI) technology, dubbed UHF-1 [1]. All four products make use of the same die, which has both NPN and PNP transistors on it. Figure 1 shows the pinouts of the four different products. Typical NPN and PNP transistor characteristics are shown in Table 1.

Antenna Beam Steering Without Phase Shifters – an ‘Old’ Technique Revisited

Antenna arrays are of perennial interest and relevance to RF wireless system designers, indeed the rise of 5G is showing their importance is only growing. Most implementations of linear arrays use phase shifters to feed the array and hence form the main-lobe beam. In the 1960s, a technique using RF switches and Fourier analysis was discovered to be a viable alternative to phase shifters called ...

On Stability and Performance of Frequency-Offset Cartesian Feedback for RF Power Amplifiers of MRI Transmitter Arrays

Introduction: We have previously proposed the use of Frequency-Offset Cartesian electronic feedback (FOCF) to deal with the rising challenges associated with control over the RF transmission fields in arrays of coils [1] [2]. In comparison to back-off, high transistor counts and other linearization methods, Cartesian feedback— like Vector Iterative Predistortion, VIP [3]—does not trade efficien...

Design of Thin-Film-Transistor (TFT) arrays using current mirror circuits for Flat Panel Detectors (FPDs)

We designed 4x4 matrix TFTs arrays using current mirror amplifiers. Advantages of current mirror amplifiers are they need less requiring switches and the conversion time is short. The TFTs arrays 4x4 matrix using current mirror circuits have been fabricated and tested with success. The TFTs array directly can process signals coming from 16 pixels in the same node. This enables us to make the su...
