Technologies for provided for a radio frequency input/output (RFIO) combiner/splitter. An example combiner/splitter can include an RFIO circuit including a receive path including first and second low noise amplifiers (LNAs), first switches, resistors, and capacitors, each of the first switches being in series with a respective one of the first capacitors and first resistors; a transmit path including a first power amplifier (PA) including second switches coupled to second resistors and third switches coupled to third resistors, and a second PA including fourth switches coupled to fourth resistors and fifth switches coupled to fifth resistors, each of the second switches, the third switches, the fourth switches, and the fifth switches being in series with one or more respective ones of the second resistors, the third resistors, the fourth resistors, and the fifth resistors; and a balun that couples the Rx and Tx path to an RFIO terminal.
