Maxim introduced the MAX1479 , the world's smallest VHF/UHF PLL-based ASK/FSK transmitter to deliver more than +10dBm output. It is housed in a small, 3 x 3mm, 16-pin thin QFN package. The transmitter ...

The UHF ASK/FSK PLL transmitter ICs ATA8401 (310 – 350 MHz), ATA8402 (423 – 439 MHz), and ATA8403 (868 – 928 MHz) are designed for low-cost RF transmission systems in industrial and consumer ...

The MAX7057 crystal-referenced ASK/FSK transmitter can operate at any frequency in the 300 MHz to 450 MHz range with the proper crystal frequency and can transmit data at rates up to 100 kb/s NRZ ...

The spectrum measured at the output (V ANT) shows that the CMOS transmitter can produce the maximum power allowed for the 40.680-MHz ISM band (10 mW) and comply with the European regulations.
