PE128300 Dual-channel Up-Down Converter

The PE128300 is dual-channel TDD up-down converter designed for 5G FR2 n257, n258 and n261 frequency bands. In transmit mode, the input to a channel is applied to IF_I and IF_Q 50Ω impedance ports. The signal passes through circuits which adjust the relative amplitude and phase of the I/Q signals. T/R switches route the IF signal to the transmit image reject.
