The AM-RX12A-433P is a radio frequency (RF) receiver designed for use in a broad array of applications that require reliable transmission of remote signals. It is a unipolar receiver, with an integrated, specialized low-noise amplifier circuit and an active bias control system, which allows for maximum performance and signal accuracy. This receiver is ideal for applications such as garage door openers, home automation systems, and security systems.

The AM-RX12A-433P is based on a super-heterodyne receiver system. In these systems, the input signal is heterodyned, or combined, with a signal from a local oscillator to yield a new signal for further processing. The local oscillator signal is typically derived by multiplying an oscillator frequency by a fixed harmonic ratio of a reference frequency, allowing for greater variability in the output signal.

In the case of the AM-RX12A-433P, the local oscillator Signal is generated by multiplying a 50 kHz reference frequency with a harmonic ratio of 24. 12 kHz is then mixed with the incoming signal to yield an intermediate frequency of 36 kHz, which is then sent through the low-noise amplifier. Once amplified, the signal is then filtered and rectified, and the result is provided on the receiver’s output.

The superior amplification of the AM-RX12A-433P RF receiver permits long-distance transmission of signals, up to 300 meters. The receiver is also insensitive to interference from other sources. The active bias control system in the AM-RX12A-433P also ensures maximum performance and signal accuracy, by automatically adjusting the bias voltage for the receiver’s FET amplifier circuits.

The AM-RX12A-433P can be safely connected directly to a micro-controller or other controlling device, as it requires only a supply voltage of 4-7V DC and consumes a maximum of 2.4 mA. Additionally, the receiver operates on a chosen frequency of 433.92 MHz, and its bandwidth is adjustable between 305 kHz - 455 kHz.

The AM-RX12A-433P radio frequency receiver is a reliable wireless transmission device, providing quality performance and signal accuracy. Clear signal transmission, even at long distances, with minimal interference, makes this RF receiver an ideal choice for applications such as wireless garage door openers, home automation systems, and security systems.
