F1370NBGI - Renesas Electronics
Description: The IDT F1370 is a highly linear complex IF digital pre-distortion (DPD) demodulator with built-in digital step attenuator (DSA) and single-pole-double-throw switches (SP2Ts). It receives the signal coming out of the PA so that the I&Q data at Baseband can be pre-distorted before being sent to the Tx DAC to counteract the distortion inherent in the downstream PA. The signal coupled from the PA is adjusted via a DSA to a lower level and then sub-sampled at an IF frequency of ~200 MHz which necessitates the
