Abstract:

This article presents a low-power (LP), compact, wideband (WB) low-noise transconductance amplifier (LNTA)-first receiver (RX) designed for software-defined radios (SDRs). It comprises the LNTA, frequency divider, mixer, and trans-impedance amplifier (TIA). The LNTA utilizes a common gate (CG)-common source (CS) structure without on-chip inductors and incorporates gm-boosting and …

Abstract:

This article presents a compact 24–30-GHz phased array transceiver (TRX) front end (FE) with high transmitter (TX) power efficiency and low receiver (RX) noise figure (NF) in a 130-nm bipolar CMOS (BiCMOS) technology supporting different 5th generation mobile network (5G) frequency range 2 (FR2) bands (n257, n258, and n261). We introduce …
