Description

The PM7819-BI is an electronic component model that falls under the product category of IC Chips. It is designed with various features to enhance performance and efficiency. The PM7819-BI provides wideband linearization of power amplifiers in wireless basestations through digital adaptive pre-distortion. It also offers digital correction for analog quadrature modulation distortion and digital soft pre-compression for efficiency management. With an input signal bandwidth of up to 10 MHz and a sample rate of up to 80 MHz, the PM7819-BI supports a programmable and variable input data rate. It is equipped with a 16-bit microprocessor bus interface for adaptive control processor compensation engine and a serial interface for updating power and carrier values. Additionally, it has 48 general-purpose IO pins, including eight edge-triggered interrupt sources, and a standard IEEE 1149.1 JTAG test port for boundary scan board test purposes.
