KU PA 190250 - 80 LIN
LDMOS Power Amplifier, 1900 ... 2500 MHz, 10 W COFDM Linear S-Band Power Amplifier
Designed for applications such as Digital broadcast systems (DVB-T, DVB-S), COFDM systems using modulation types QPSK, QAM and Multichannel Multipoint Distribution Service (MMDS) the KU PA 190250 - 80 LIN is a highly capable linearized power amplifier for high linearity and high data-rate applications. The unique feature of RF-predistortion compensates for inherent non-linearity of power amplifiers and guarantees exceptional low EVM levels.
