摘要：

This paper presents a compact, highly linear Ku-band SiGe HBT PA for Low Earth orbit (LEO) satellite communication (SATCOM). A four-way output transformer (TF) balun with a shared single center-tap (SSCT) is proposed not only for simplifying signal routing for compact chip size, but also obtaining high power combining efficiency. A prototype Ku-band SiGe PA, which merely occupies a core area of 0.21 mm(2), attains measured peak output power (P-OUT) and power added efficiency (PAE) of 24.4 dBm and 32.1% at 11.7 GHz, respectively, with the highest power density of 1311.5 mW/mm(2). The PA also delivers average P-OUT (P-avg) of 18.6/16.6 dBm with average PAE (PAE(avg)) of 16.0/12.6% at 250 MHz symbol rate DVB-S2X 64/256 APSK modulation.
