Description

The TX3A transmitter module uses a frequency modulated crystal-locked PLL and operates between 2.2V and 16V at a current of 7.5mA nominal. At 3V supply it delivers nominally 0dBm (1mW) RF output. The SIL style TX3A measures 32 x 12 x 3.8 mm, excluding pins.

The TX3A module is a single conversion FM superhet receiver capable of handling data rates of up to 64kbps. It will operate from a supply of 2.7V to 16V and draws 11mA when receiving.

The TX3A features a fast power-up time for effective duty cycle power saving and a signal strength (RSSI) output with
60dB of range. Full screening and a SAW front-end filter give good immunity to interference. The SIL style RX3A measures 48 x 17.5 x 4.5 mm, excluding pins.
