DESCRIPTION

The AM-TX1 Transmitter module offers a miniature hybrid modular RF transmitter providing on/off keyed

(OOK) modulation, which can be used to transmit data from any standard CMOS/TTL source up to 1200

baud.

The module is very simple to operate, requiring only two connections (see application circuit below). The

module is also very efficient, using only 2.3mA (typ) which means that it may be driven directly from an en-

coder I/C or microcontroller. The output impedance has been designed to give optimum performance when

coupled with a small antenna such as a tuned loop or short whip.

The modules are compatible with the AM Receiver module (AM -HRX3-XXX).

Order Code: AM-TX1-4xx
