Frequently Asked Questions
What modulation schemes does the ATA8403C-6AQY66 support for industrial wireless links?
The ATA8403C-6AQY66 supports both ASK (Amplitude Shift Keying) and FSK (Frequency Shift Keying) modulation in the UHF band, giving designers flexibility to comply with ISM-band regulations at 433 MHz or 868 MHz and to optimize between range and immunity to adjacent-channel interference in industrial environments.
How does the ATA8403C-6AQY66 supply current affect battery life in a handheld remote control?
With a maximum supply current of 11 mA at 3 V and a duty-cycled transmit schedule, a pair of AA batteries (roughly 2500 mAh each) can sustain tens of thousands of button-press transmissions. At 10 ms TX bursts and 1 press per minute, average current drops well below 1 mA, enabling multi-year battery life in typical remote control usage.
Which package does the ATA8403C-6AQY66 use, and how does it simplify PCB layout for a transmitter module?
The ATA8403C-6AQY66 comes in an 8-pin TSSOP package (0.65 mm pitch, body approximately 3 mm x 4.4 mm), providing a small footprint that fits within compact RF module PCBs. The 8-pin count covers power, ground, data input, frequency-setting, and antenna output pins, minimizing external component requirements for a complete transmitter circuit.
