“…The core-chip (CC) is a mixed-signal highly-integrated multi-function MMIC performing all the core controlling functions of a TRM, i.e., path setting, phase shifting, amplitude control, together with low-level amplification at microwave frequencies from Sto Ka-band [1][2][3][4], while the high-level amplification functionalities are typically entrusted to a second dedicated MMIC, the front-end (FE), nowadays typically implemented in GaN technology [5,6]. To achieve accurate beam control, the number of control lines required within a CC can be very high, in the order of tens, and may thus represent a major issue in large AESA systems.…”

Microwave core-chips are highly integrated MMICs that are in charge of all the beam-shaping functions of a transmit-receive module within a phased array system. Such chips include switches, amplifiers and attenuators, phase shifters, and possibly other elements, each to be controlled by external digital signals. Given the large number of control lines to be integrated in a core-chip, the embedding of a serial to parallel interface is indispensable. Digital design in compound semiconductor technology is still rather challenging due to the absence of complementary devices and the availability of a limited number of metallization layers. Moreover, in large arrays, high chip yield and repeatability are required. This paper discusses and compares challenges and solutions for the key sub-circuits of GaAs serial to parallel converters for core-chip applications, reviewing the pros and cons of the different implementations proposed in the literature.

“…Modern phased array antenna systems consist of many transmit/receive modules (TRMs). To make the systems economically attractive, a cost reduction of these TRMs is essential [1]. The cost of a TRM is mainly determined by the total number of assembled monolithic microwave integrated circuits (MMICs).…”

“…While several S-band multifunction MMICs have been implemented using GaAs technology [1]- [3], no reported chips have included an SPC. Hek and others [1] reported a fully integrated S-band multifunction MMIC without an SPC. For the chip control, as many as twenty-six interfaces may be required.…”

An S‐band multifunction chip with a simple interface for an active phased array base station antenna for next‐generation mobile communications is designed and fabricated using commercial 0.5‐μm GaAs pHEMT technology. To reduce the cost of the module assembly and to reduce the number of chip interfaces for a compact transmit/receive module, a digital serial‐to‐parallel converter and an active bias circuit are integrated into the designed chip. The chip can be controlled and driven using only five interfaces. With 6‐bit phase shifting and 6‐bit attenuation, it provides a wideband performance employing a shunt‐feedback technique for amplifiers. With a compact size of 16 mm2 (4 mm × 4 mm), the proposed chip exhibits a gain of 26 dB, a P1dB of 12 dBm, and a noise figure of 3.5 dB over a wide frequency range of 1.8 GHz to 3.2 GHz.
