ATA5428 (ATA5423 - ATA5429) UHF ASK/FSK Transceiver

The ATA5423/25/28/29 is a highly integrated UHF ASK/FSK multi–channel half–duplex transceiver with low power consumption supplied in a small 7 x 7 mm QFN48 package. The receive part is built as a fully integrated low–IF receiver, whereas direct PLL modulation with the fractional–N synthesizer is used for FSK transmission and switching of the power amplifier .
