Cyf119b 300MHz to 450MHz Transmitter IC

CYF119B 300MHz to 450MHz Transmitter icDESCRIPTION:CYF119B is a high-performance, easy-to-use single-chip ASK transmitter IC, suitable for long-range wireless applications in the 300-450MHz frequency band. This chip is a monolithic device that can truly achieve "data input, antenna output". CYF119B has three powerful attributes: power output, working voltage and working temperature. CYF119B can provide +14dBm for 50Ω load. This power level allows small transmitters (lossy antennas), such as key fob transmitters, to operate near the maximum limits of the transmission rules. 2.0V to 3.6V operating voltage, CYF119B can be used with most batteries, reaching the limit of its use range. The operating temperature range is -20°C to +70°C.CYF119B is easy to use. It only requires some additional external components and a crystal to generate a reference frequency (RF carrier frequency divided by 32 times), which is enough to create a complete multi-function transmitter.CYF119B adopts ASK / OOK (Amplitude Shift Keying/On-Off Keying) UHF receiver type, ranging from broadband super-regenerative radios to narrow-band high-performance super-heterodyne receivers. The maximum ASK data rate of is 10kbps (Manchester encoding).CYF119B transmitter solution is very suitable for simple and important industrial and consumer applications.  FEATURES:                           Complete UHF transmitter;300MHz to 450MHz frequency range;ASK modulation data rate up to 10kbps;Output power reaches +14dBm;Few external parts needed;Low voltage operation (down to 2.0V);Use crystal or ceramic resonator;Power-down mode and wake-up function to reduce power consumptionPackaging: SOT23-6ApplicationsFan controllerRemote power switchMultimedia remote controlRemote sensor data linkInfrared transmitter replacement/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
