PE128300 Dual-Channel Up-Down Converter

pSemi PE128300 Dual-Channel Up-Down Converter is designed for 5G FR2 n258 and n257 frequency bands in the 24.25GHz to 29.50GHz range. In transmit mode, the input to a channel is applied to IF_I and IF_Q 50Ω impedance ports. The signal passes through circuits that adjust the relative amplitude and phase of the I/Q signals. T/R switches route the IF signal to the transmit image reject mixer. Next, the up-converted signal is either directly connected to an RF amplifier or, in the packaged case, is routed through a bandpass filter inside the package and amplified afterward. The RF amplifier outputs route through T/R switches to IC bump contacts.
