1. Description
The ATA8402 is a PLL transmitter IC, which has been developed for the demands of
RF low-cost transmission systems for industrial applications at data rates up to
50 kBaud ASK and 32 kBaud FSK modulation scheme. The transmitting frequency
range is 429 MHz to 439 MHz. It can be used in both FSK and ASK systems.

    ... ASK modulation. 4.1 ASK Transmission The ATA8402 is activated by ENABLE = H. PA_ENABLE must remain L for t 1 ms, then the CLK signal can be taken to clock the microcontroller and the output power can be modulated by means of the PA_ENABLE pin. After transmission, PA_ENABLE is switched to L and the micro- controller switches back to internal clocking ...

Do not confuse this large signal load impedance with a small signal input impedance delivered as input characteristic of RF amplifiers and measured from the application into the IC instead of from the IC into the application for a power amplifier ...
