WEA520SFMCW22G

The WEA520SFMCW22G is an ultra-fast ultra-linearFMCW frequency synthesizer capable of generating 1400MHz Chirps at 20 GHz frequency. It uses a reference inputranging from 20 MHz to 200 MHz, with the use of anexternal Crystal or clock (CMOS or LVDS). TheWEA520SFMCW22G generates an RF signal spanningfrom 7.0 GHz up to 20.25 GHz with the four integratedVCOs and the use of an RF frequency doubler and divider.The synthesizer utilizes the WEASIC proprietaryWeCHIRPTM, wePACTM, weCALTM technologies to providevery fast ramp retracing and settling times whilemaintaining industry leading phase noise during chirping.The modulator has a phase synchronization capability forcoherent operation with other modulators. It alsoprovides synchronized trigger event signals for theRADAR Transmitter and Receiver chips. By the use ofinternal high PSRR LDOs, the WEA520SFMCW22G canwithstand noisy power supply environment. It is poweredby a single 1.8 V supply
